Category: GameBoy Advance

A new build of the Gameboy Advance emulator No$gba has been released. Here is the changes for 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)
