Snezziboy v0.22 released

[Robert]

SNES emulator for GBA

 

v0.22

------

 

Bug Fixes:

 

- Fixed the JMP ($xxxx) and the JML [$xxxx] instruction to read the indirect addresses from bank zero instead of the current data bank. (Aero fighters now work)

- Shifted the horizontal offset by 8 pixels to the right so games now look generally centralized

- Modified the IO for WRAM write at IO addresses $2180-3 to behave as Snes9x

- Fixed the interrupts to push the correct program counter onto the stack, and the RTI instruction to pop the correct program counter from the stack. (Earthworm Jim now works)

- Fixed the $213C/D registers to generate the H/V counters correctly. (Zelda-A Link to the Past now works, though in the name entry screen, the name selection still does not move, and in-game text is invisible...)

- Fixed the COP instruction to fire a COP interrupt (Illusion of Gaia now intros correctly)

- Fixed the MVP/MVN instruction to increment the cycle counter correctly.

- Fixed the DMA such that source DMA address is incremented and the DMA size is set to 0, after each DMA channel read/write is complete. (Contra's intro and in-game background tiles display correctly now) (FF2 non-mode 7 backgrounds now displays correctly) (Illusion of Gaia title screens appear)

- Added rendering for Modes 4 and 5. (Secret of Mana name entry screen requires mode 5, and now appears better. Due to double horizontal resolution though, the text appears but remains unreadable)

- Added the $2139/A registers to read the VRAM. (Illusion of Gaia seems to works perfectly) (MegamanX, Megaman7 screens get restored after pressing start)

- Added option for enabling backdrop (With this option set to Yes, Super Mario World backgrounds will not appear black)

 

Others:

 

- Provided additional SnezziDebugger.exe that can be used to debug SNES games to search for speed hacks, SPC patches and other patches.
