Casio Calculators / Re: FX-cg Manager add-ins speed issues
« on: April 29, 2012, 08:25:34 am »
Yes, some games (like Rainbow Dash, Gravity Duck and Sonic) automatically overclock on start.
It would be better to detect if the program is running on emulator (maybe with Simon's proposal) and overclock only if not.

@Simon : on the emulator, syscall 0x1196 returns 0x00, but if I read directly the byte at 0xA0000305 I get 0xAA.
BTW, it's off-topic but do you know a Sleep syscall ? I think we need it, until now all games use 100% of CPU so they drain batteries. I know this function use TMU2 on fx-9860, maybe we can write an equivalent routine for Prizm.

On the emulator, if you overclock or underclock, the result is the same, it becomes very slow.
Example with Gravity Duck :
without overclock : emulator=50FPS, calc=15FPS
with overclock : emulator=6FPS, calc=25FPS

In a lot of game, the map is a table where each cell contains a tile. Some of them are solids, others not.
Example in Mario, each block is a tile :

Mario is as wide as the tiles, so he can to be on 2 tiles at the time. So you have to check these 2 tiles under him to know if Mario can fall down.

This week end, there is 48h CPC #3 !
Make an addin for Prizm. The theme will be unveiled in less than 2 hours (midnight in France, GMT+2)
The deadline is Sunday 22 april, 10:00 pm (GMT).

The game detect the CPU speed at launching, if it's less than 94.3MHz the game set speed at 94.3MHz, and at quit it restore the speed as it was before launching. :)

Update, Beta 2
I've added the main menu, and pause menu, and also overclock to improve speed (thanks to Ashbad).

Thank you guys, with you we have 9 entries, for a programming competition on 48h, it's exceptional.
Your games were linked on the official topic of this second 48h CPC.
Results will be given in 1 or 2 weeks max.

About the deadline, I made Gravity Duck for the first 48h Casio Programming Contest ;)

Just open the COM port on 9600 bps, no parity, 8 bits and output byte 0x55 in a loop.

Thanks :)

Hi all, thanks for the news.
Indeed, I don't have Prizm, so I use the Casio fx-CG Manager to test my programs and to make screenshots (I use it on a virtual machin, when trial time is over, I reset the VM).
The big problem on this game is the speed, 50FPS on emulator, 15FPS on calc. I'm searching trick to improve it.

Nobody in calculator communities makes monnay with its programs, so why close the sources ?
Open source is good for the community. We only work for fun, and your sources can help someone in the world.
Always give your sources !

CasioKingdom may close one day, and a lot of programs are only there. This pack is a good backup.

Hey MPoupe, I just unexpectedly found the sources of this program in a corner of my hard drive, and it amused me because it use exactly the same idea than one of my programs ^_^

@vxl : if you want to talk in french about Casio, you can also come on planet-casio :)

LuaFX est simplement l'interpréteur Lua adapté pour calculatrice Casio. (FX fait référence à fx-9860, et LuAFX fait aussi référence à la Graph 100, AFX).
A noter qu'il existe aussi depuis longtemps un interpréteur Lua pour Classpad ;)

Casio Calculators / Re: Prizm image compressing algorithm
« on: November 30, 2011, 12:02:53 pm »
I use a simple compression by using a color swatch, and size of all bitmaps is divided by 2 (plus some bytes for the color swatch). It work fine :)
