Snezziboy v0.25 - Snes Emulator for the Gameboy Advance

***wraggster*** · August 10th, 2006, 17:44

Snezziboy the SNES Emulator for the Gameboy Advance (nintendo ds too) has been updated, heres whats new:

Fixes and Features:
- Fixed a bug with the reading of registers $2137/$213C/$213D (Final Fantasy Mystic Quest is able to proceed to the title screen)
- Fixed a critical bug with the MVN/MVP instructions to handle the A register correctly in 8-bit mode.
- Fixed a DMA bug so that the incrementing of the source address does not affect the address bank. (Final Fantasy Mystic no longer crashes and now seems playable)
- Fixed a bug with the DMA transfer to correctly increment the source address depending on the DMA increment mode. (Secret of Mana no longer crashes before the first dungeon) - Fixed a bug with the RESET function that causes backgrounds remain stationary after using the configuration's RESET option.
- Fixed the SBC instruction to take care of decimal mode subtraction (uses modified code from SNES Advance) (Zombies ate my Neighbors is now playable)
- Fixed Mode 7 where there was once a band appearing at the top of the screen.
- Fixed (partially) SNES additive transparencies. - Implemented Mode 7 wraparound based on register $211A. HDMA: - Implemented partial HDMA for background scrolling positions (Donkey Kong 3, first level moves as expected) (Street Fighter 2 background moves as expected) (Castlevania X first level background effects visible) (HDMA is slow on the GBA and is expected)
- Implemented new option to enable/disable HDMA (for games that don't necessarily require it)
Optimizations:
- Made slight optimizations to instructions that operate on the A register, and certain jump instructions
- Made major optimizations to all instructions to remove instruction to add to SnesPC register (Credit to Gladius for the suggestion; most games should experience a slight but notable increase in speed)

Wow, alot of updates! Nice release!

I am having a problem though... I dragged the ROM to snezzi.exe, then put it through the M3 game manager through NDS mode direct copy, just like on the .24 version. But the ROMs won't start up.... is there anything I'm doing wrong??

Not sure about m3, but you said you used NDS mode, and this is snezziboy (for GBA), not snezziDS.

I was able to run everything fine booting in NDS mode for v.24-patched roms, and unlike GBA mode it had sound, and 2 extra buttons. It was also faster. All the games I converted for v.24 don't work for v.25 in NDS mode, and they run slower, without sound in GBA mode...
