Re: UCC2014: The Uzebox Code Challenge is back!
I was writing a nes emulator for uzebox, could I enter it on the UCC 2014? Is still in early stages of development, and I just wrote the 6502 cpu emulation code, but is not working right yet, there's still some strange bug preventing some opcodes to write on memory :evil: , but is pretty possible. N...

Re: Uze8 - Chip8/SChip emulator!
Today I found a bug that was causing some chip8 games to only show black screen (like rush hour). Already fixed.
Version 2.0 will be released soon, with several interesting news! Stay tuned!

Re: Game uzebox
well, is easy to see that your primary language is not English. This issue has been discussed a few times,there's a game called UzeMario that load levels from files on SD Card, like you said. Take a look at the uzebox championship topic.

Re: problems with threaded uzem
should I just stick with WinAVR even though it is several years out of date, or should I update the GCC parts of it. If so is it dangerous and can I break thing trying to update the GCC version. I use avr studio 6 with WinAVR-20100110 and all I've tested so far works without problems. :D You can ev...

Uze8 - Chip8/SChip emulator!
As you may have seen, I've been working on an chip8 emulator for Uzebox these days. The major limitation of Uzebox is the small Ram, with only 4k. Making an emulator with 4k of RAM is an almost impossible task. However, chip8 is a simple system which have only 3.2 kb of RAM. Thanks to help from Uze6...

Re: Chip 8 emulator for Uzebox
http://img545.imageshack.us/img545/6537/2v9g.jpg Thanks, the file browser is already running. The emulator will have only one Rom built in, and the other games will be loaded from the sd card. Maybe I'll add an option to save and load states later. Now I just need to make some small changes on menu...

Re: Chip 8 emulator for Uzebox
Speaking of optimizations, when looking at your code, it's not clear if you are actually using the first 512 bytes of your memory[] array? In fact, the VRAM of 64x32 mode uses this area, but occupies only 256 of the 512 bytes. The font of chip8 can be loaded from flash, as it doesn't change at runt...

Re: Chip 8 emulator for Uzebox
With PetitFS is loading fine, even though it requiring little RAM, I still had to do some optimizations. I had to put the registers V0-VF inside chip8 memory (the 0x151-0x160 area) to save RAM, now the code is a bit confusing. :? I still have to fix a bug that appeared - the game rush hour stopped w...

Re: Chip 8 emulator for Uzebox
It didn't worked :( I tried several ways to implement your code to load the game, but it just shows a blank screen. Below I am attaching the code, I was testing the game "maze", which only has 34 bytes, renamed to "game.ch8", copied to sd card and it didn't work. Uze8_sd.zip Edit...

Re: Chip 8 emulator for Uzebox
http://img96.imageshack.us/img96/2315/t6xe.png I redid the menu, and now is much better. Just needs code to load games from sd card, fix the sound emulation and add customized colors for each game. Tomorrow I should have everything ready. Suggestions are welcome! Edit: I couldn't find anything abou...
