GBA/NDS emulator

18th June 2006 - version 2.2f

 

- cpu/help: added CPU Memory Alignments chapter (and info on mis-alignments)

- research: discovered wglCreateContext (despite no info in worst opengl specs)

- gba/video: hides invalid tiles in NDS-in-GBA-mode (invisible, unlike real gba)

- gba/video: shows invalid tiles in GBA/SP-mode (vertically striped) (jasper)

- gba/help: unprectiable things: described invalid tiles (thanks jasper vijn)

- gba/emu/help: corrected Prefetch Disable (1N+1I instead 1S+3I) (jasper vijn)

- gui: re-fixed game_template for multiple machines (@@total for dual-screen)

- nds/vram: nds7 emulated vram mirrors every 256K, disabled palette/oam access

- nds/vram: nds9 ignores 8bit-writes to vram/palette/oam (thanks gary linscott)

- nds/vram: nds7 allows 8bit-writes to vram (thanks gary linscott)

- cpu: ignores mis-alignment on NDS9 LDRH/LDRSH (unlike rotated GBA/NDS7 data)

- nds/debug: filesystem viewer rejects invalid nds headers (eg. passme files)

- nds: emulates reading 8bit/16bit-fractions from 32bit ipc_fifo_recv register

- cpu: emulates "ldr pc,[mem]" with misaligned jump-dest (with optional warning)

- nds/video: avoids divide-by-zero crashes in 3D perspective divisions

- gba/nds/video: speedup: color special effects by 1x32bit mul (instead 3x5bit)

- nds/help: fixed extended palette enable bits (dispcnt bit31,30 exchanged)

- a22i: supports macros (still without params) (.macro  /... /.endm)

- a22i: supports repeat macros (.rept  /..code or data.. /.endm)

- nds/video: emulates new nds master brightness up/down effect (port 400X06ch)

- vram viewer: supports NDS rot/scal mode with text-style 16bit bgmap entries

- gba/vram/emu/help: strb to vram: write-nothing reduced to 16K in bitmap mode

- gba/vram/emu/help: strb to vram: write-twice expanded to 80K in bitmap mode

- nds/video: new rotscal mode with 16bit map entries (400h tiles ext_pal xyflip)

- nds/video: extended palettes (256-color TEXT, 256-color OBJs, 16bit rotscal)

- nds/video: emulates large screen bitmap mode (not tested, but should work)

- nds/reset: also zero-fills 2D Engine B ports (bg0ofs scroll registers, etc.)

- cartloader: loads.NEF debug-info also for.NDS files (instead only for.SRL)

- cpu: allows mis-aligned thumb BX R15, auto-aligned to "($+4) AND NOT 2"

- gba/video: emulates obj-wrap; 64x64 scaled to 128x128 only in UPPER portion

- nds/help: described obj-wrap; 64x64 scaled to 128x128 in BOTH screen portions

- nds/video: screen-width for NDS rot/scal-obj (256 pix on NDS, instead 240 pix)

MAMETesters Bugs Fixed

---------------------------

wboysys2_0106u4gra [Canim]

 

 

Source Changes

------------------

Minor fix for x64 compilation support with MSVC. [Malice]

 

Updated astdelux and omegrace built-in overlays for the new render system.

 

Fixed inputs in the mcr68 drivers. [Peale]

 

Fixed new debugger support for custom register lists. [Tim Schuerewegen]

 

Added workaround to make the V60 core work properly on GCC 4.x (tested on 4.1.1). [R. Belmont]

 

Fixed the drc blitters better. [Olivier Galibert]

 

Improvements to Polygonet Commanders: [R. Belmont]

* Fixed Z80 IRQ/NMIs to go to the right CPU again

* Modernized memory map

* Added network status bit, so the initial test passes well enough to make the DSP56k crash on unimplemented opcodes

 

Miscellaneous cleanups to the Atari/Max-A-Flex driver, attempting to modernize it. [Nathan Woods]

 

Updated Sega multi-32 driver to support multiple screens. [Aaron Giles]

 

Backed off of the multithreading for the moment in order to focus on getting the rest of the kinks out of the new renderer. All the infrastructure is still in place and can be re-enabled by flipping the ENABLE_THREADS flag in window.c. [Aaron Giles]

 

Added support for "stretch to fit" when configuring a render target. Added back the "-keepaspect" option as a result. [Aaron Giles]

 

Added clamping to the prescale effect so that it doesn't try to create excessively large textures. Explicitly reset render states so that the prescale step is not filtered. Fixed StretchRect usage so that it doesn't filter on some video cards. [Aaron Giles]

 

Fixed behavior of pixel aspect ratio when configuring render targets (was correcting in the wrong direction). [Aaron Giles]

 

Moved thread priority logic out of ticker.c and into winmain.c where it really belongs. [Aaron Giles]

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.
