False authors

It's not really that surprising when you think about it, but there have been a couple pages where I find that the author listed was modified or incorrect, seemingly intentionally. This page will track the pages where I know this issue occurred.

This post is also a reminder to myself for the future to check pages more closely to see if there are any more of these...

  • NIGHT RACE - original submitter claiming credit was not the author
  • Attack on Titan Tribute Game - modified a few years after submission by a seemingly random user

Do more exist? I have no idea, I found both of these by accident. I suspect there may be more, hence this post. If you uploaded programs here at some point, check your own pages to see if they are correct.

Extension ideas

At this point I think it's clear that some very cool things are possible via PTC-ASM or similarly designed projects. Here's a list of other idea's I've had that I'm not likely to implement (at least not soon) but I believe would be possible if someone wanted to try.

  • GTRI function

This probably wouldn't be too hard to implement. The only "tricky" part would probably just be dealing with pixelCHR coordinates (efficiently at least). Even so, this idea is pretty straightforward.

  • PRG* functions

I suspect this would be possible based on the format of program data being a bunch of separate lines. This would be still somewhat complicated for a couple of reasons - one is that there's some sort of processing step that converts functions, commands etc. i…

Some function notes

More notes about internal stuff. This is once again not a complete page, but may still be useful.

All of the following information is for a USA copy of Petit Computer 2.2.

There is a function at 0x01ff9a54. This seems to be the "evaluate one expression" function. It accepts a pointer to the "main/DIRECT DU" and returns an error code if necessary (or 0 for success).

There is a function at 0x01ff9d90. This seems to skip spaces, as far as I can tell, with some sort of unclear extra logic relating to how much can be read? This also takes a pointer to the main DU, and returns a value indicating whether or not the last character was a space (maybe?) that seems to usually be ignored?

There is a function at 0x01ffa160 that takes 3 arguments. This seem…

More memory research

This isn't complete enough to get a page yet, but it's still interesting and worth sharing so let's write down some of the memory regions.

Disclaimer: Double check the addresses - some of them end up off by a bit if I misread a structure or forget to check the main DU address

A note about these pointers: These all point to what I am calling "Data Units" because the start of each is 0x44,0x55,0x00,0x00 "DU\0\0" followed by a size, a pointer to the previous/next unit, and a pointer to the next/previous unit. It looks like a doubly-linked list, maybe it's related to memory allocation? Some of these addresses/sizes may change if you load/save files. My (successful) tests always go Launch PTC -> Write Program. If I scan a QR code first, it seems …

Remaining PTC Projects II

It seems my previous post is somewhat lacking in the stuff I've been doing lately, so this is the sequel focused on projects for PTC instead of projects in PTC.

  • 1 The list:
    • 1.1 PTC-Interpreter and PTC-EmukII -
    • 1.2 Partial-SSEQ-Player -
    • 1.3 PTCTools -
    • 1.4 Research into petit-compwner related ideas
  • 2 Summary

Since my last post, PTC-Interpreter was started, stalled, and completely recreated as PTC-EmkII. Currently, it supports a pretty solid amount of the sample programs, and has decent compatibility with some other programs as well. I know Tales From The Labyrinth and Village both run, but have some issues. Updates have slowed down whil…

So, I made this account on 9/12/2013 it seems ...

I can track my edits back to September 2013 but it seems that Fandom is too shitty to show one's join date anymore, so I'm going with my memory that it's 9/12 (I specifically waited until after 9/11, I'm pretty sure).

Gosh, that's 9 years ago: I was 12!

Maybe I'll remember that now that I've written it down? Perhaps not. It's nice to remember how long I knew those, though.

How active is the Petit Computer community these days?

There's like an achievement badgey thingy whatever for making a blog post, so I might as well ask this here. Do people still use this thing, or has everyone moved on to SmileBasic and this place is just some kind of ghost town now?

I don't have a 3DS, and I'm still waiting for the localization of the Switch version... sigh.

any OGs left ?

7 years ago, when i was 11 years old, i saw an ad for petit computer somewhere online. i've always been interested in computers and programming and when i discovered the program, a cheap app that allowed you to write your own apps and games directly from your 3DS/i for less than $10 i was all over it; bought it as soon as my dad got me an eshop gift card. i toyed around with it a little bit on my own before stumbling upon this community. i scanned some QR codes, made some cool little apps of my own and contributed to a few others. although the program itself was pretty cool and unique, the community at that time was great. small, cooperative (for the most part) and pretty mature given most of us being in middle school or just starting high…

Remaining PTC Projects

Guess I'll post something about all the stuff I am working on or need to finish. Might as well figure out what to focus on. (this is more or less a to-do list)

I still want to finish this - I've been fixing parts of it, but haven't had a great deal of time to focus on this. Right now, the editor is fine, but the gameplay is glitchy and getting it to run at full speed is difficult. If I can solidify the enemy physics, it would actually be very close to done - but I'm struggling getting physics to work correctly.

I actually have some ideas for my old game - I haven't finalized any of them, but a few new modes and some HUGE optimizations could be added. At some point I would like to create this as a phone game, since the design of it is fairly …

  • 2 FLIPS
  • 3 HOP
  • 4 PAINT
  • 6 SHOOT
  • 7 SHOOT2

Throughout my time of using Petit Computer, I've learned plenty of things, many of which have been invaluable to later projects. Sometimes, I put these things into practice through tiny little tests that I'll never release. But sometimes, I make bigger, more ambitious, tests. These may never become fully developed games at my own hands, but maybe somebody else can take over or use the code for their own purposes.

These projects deviate from my standard Desaeta License that I apply to all of my completed projects. All of these are completely free for you to use. I could care less if you call these your own and …

RPG Editor Part 4

Just a short update on how everything is going so far.

There are still some difficulties combinig the different parts.

Right now there are a lot of unexpected errors combining the map editor with the quest system, so it is easy to define a trigger area for various events.

So it will probably need like between one or two months until the first video will be released, showing the possibilities of the different program parts.

J8B's Virtual Bébête, Work in progress

Hi, it's J8B,

I'm working on a project called "Virtual Bébête" for Petit Computer.
The principle of the game is a sort of a virtual pet/sim's life, so it will be very long to finish.
A lot of mini games are planned to win money or study or find love...
There are 9 places to visit that have each 4 rooms.
For the moment, i made all the moves in the different places, you can pee, take a bath, play two card's games at home(one of them is poker), you can go to the casino and play a sort of craps, roulette and poker(same at home) and bet money.
Actually, i work on the first job of the casino, which consists of interrogating 3 suspects to find the one who cheated at the games.

For fun, i draw this cover:

RPG Editor Part 3

A few information about how the Editor works:

Control: The character is controlled with a gcircle drawn on the touch panel to achieve more directions of movement.The buttons are used to switch weapons and use items or skills, to roll or to aim (with range skills)

{This is connected to the skill and item database}

Item: Here you can configure the Item with picture,the color, the rotation, the parameters influenced by the item, buffs or debuffs,values, stacks and some more.

{buffs and debuffs are connected to the skill database}

Skill: Parameters for the skills are picture,color,rotation,animation with animationspeed, skill range, flying speed if ranged, hitbox, cost, buffs and debuffs,hitanimation, damage, cooldowns, requirements etc.

RPG Editor Part 2

I have finished the open world map System,it uses scred files, so you have no endless loading time in or before the game.

The problem is that it uses a lot of scr files, so it means a lot of download work, but it is pretty easy to append a screen on the left or right side or wherever you want in the map, so make a dlc or a new map part for a sidequest for example should be very easy.

I am also going on connecting different data bases.

For exampls you have one program to define skills with hitbox, animation, damage, etc. and one program where you can make data for an enemy, but now you can connect the ability to the enemy.

I also made this with items and quests.

I will probably release a demo part to show how it looks like and how it will work.

Hallo :3 u guys might remember, but I might seem like a stranger to the n00bees. I'm an OG who used to go by Bug, but because of my intense use of alternating caps, I had several mispronunciation or misspelling of my name. I was suspended by the m0dz in 2014 (i think) for cursing but that didn't last long before I returned under the same alias.  I'm not going to be active 24/7, or at all.

Nothing else...? Really?

Hello, everyone; I'm creating this blog post because I want to know if there are people working in PTC projects. I guess, 99% of people are in SmileBasic projects; I'm wrong?

This Wikia is so empty right now; no new pages, no new blog posts, only a few comments a nothing else...

I have a lot of PTC projects more but I don't know if work in them or stop them...

I want to know your opinion, please. ;-)

From PTC to Steam

Well, araving at this situation, I'm happy to say that I'm programing some PTC in PC, and in the future I want to release him in some online shops, like Steam. Is not an easy or a short work (its obvious). For now, this are the games planned:

My first game that I released in this wikia, I want to apply the next feature:

  • 99 Combo mode
  • Endless mode with online rankings
  • Friends list and records exchange or online live competition.
  • Special stages, like a "777" stage like a casino
  • Modern-office stylish graphics.

Features planeed:

  • 365 days of history
  • More than 100 different dreams (planeed for now)
  • To many forms to get out the current dream... or get an epic jumpscare in your face.
  • Claustrophobic style
  • Maybe it can be a good idea to get the support of the O…

Give up sometimes

I was working on an RPG for PTC for months, but every new feature, every new attempt to try to debug my program, I just added waaaaaaaay too much in the UI, the battles, etc. It absolutly sucked every time I start over. I try porting DAYNIGHT from the TORCH demo, but it wasn't as easy as appending the program, there was a bunch of goobledygook in the comments. Probably secret code or something, that'll be interesting.

So I changed the RPG mechanics into a practice moving system for my Link's Awakening. Adding a bunch(not yet really) of debug interface on the bottom. But it's turning out quite nicely. Quite honestly, I just stole the Zelda song from Petit Forest. (Tee Hee Hee)

go dance mechanics/physics/math

alright, here comes some math. when I was designing my go dance game in the two and a half days of rushing around programming, I needed to come up with a way to get arrows to move across the screen. and, as always, there was only one way to do it: math. I first started with the rate to spit out arrows. my first songs were both at 100 beats/min, and so I needed to find some way to spit them out at 100 a minute. so, in order to find the frequency of the notes(Hz{units/second}), you need to take the beats/min divided by the time, but I needed the period, which is the inverse of frequency, in other words, time/beats/min. so the amount of time that one beat takes up at 100 beats/min is 60/100 which is .6 seconds. but that doesn't do me any good…
