New WIP up.
This one merges the most recent DSP-3 / DSP-4 work. Not sure if it
fixes any bugs or not, but good to be up to date, right? Testing would
be appreciated.
I also cleaned up the cart stuff a bit. Nicer enums,
removed some unused variables and such.
Then I turned all of the special chip class object pointers into
actual objects. It was kind of stupid to dynamically create them all,
and was just wasting performance.
I also finished adding all of the SuperFX registers, and mapped them
all to the GSU interface range ($3000-$32ff). Fixed an oversight with
the mapping, and added a new PCB database entry to get the memory map
for Yoshi's Island perfect. If you want to hear something nice, try
loading the USA version in this WIP with sound + speed regulation
enabled.
Then I added a 'Show FPS' option to the misc menu. I also didn't
realize I was still embedding the SNES controller bitmap even though
it wasn't displayed anywhere, so for now that's been removed. Makes
the EXE and archive a bit smaller.
Lastly, I redid the bsnes section of my site to look a little more
polished. Getting ready for 10/14. I've always hated the way SNES
emulator authors always cherry picked most of their screenshots to
show off their special chip support (jealousy because I didn't have
any for a long time), so I decided I'd do the exact same thing myself
this time :P
Ripped off Overload yet again, this time I stole his screenshot
layout style. Sorry, Overload ... but imitation is the sincerest form
of flattery, right? :)
Also, note that all of the ?page=bsnes_* URIs have changed to
?page=bsnes/* ... so if you get redirected to the main page from a
bookmark or something, that's why.
Whew, busy day today ...

bsnes Version 0.024 Author: byuu -------- General: -------- bsnes is a Super Nintendo / Super Famicom emulator that began on October 14th, 2004. The latest version can be downloaded from: http://byuu.org/ Please see license.txt for important licensing information. -------------- Shortcut Keys: -------------- Esc - Toggle menubar visibility F11 - Toggle fullscreen ------------------ Known Limitations: ------------------ S-CPU - Invalid DMA / HDMA transfers not fully emulated - Multiply / Divide register delays not implemented S-PPU - Uses scanline-based renderer. This is very inaccurate, but few (if any) games rely on mid-scanline writes to function correctly - Does not support FirstSprite+Y priority - OAM / CGRAM accesses during active display not supported correctly - RTO flags are not calculated on frames that are skipped when frameskipping is enabled. This provides a major speedup, however it will cause in issues in games that test these flags, eg the SNES Test Program Electronics Test. Turning frameskipping off will allow RTO flag calculation on every frame Hardware Bugs - S-CPU.r1 HDMA crashing bug not emulated - S-CPU<>S-SMP communication bus conflicts not emulated --------------------- Unsupported Hardware: --------------------- SA-1 Coprocessor used in many popular games, including: - Dragon Ball Z Hyper Dimension - Kirby Super Star - Kirby's Dreamland 3 - Marvelous - SD Gundam G-NEXT - Super Mario RPG Super FX Coprocessor used in many popular games, including: - Doom - Star Fox - Star Fox 2 (unreleased beta) - Super Mario World 2: Yoshi's Island SPC7110 Coprocessor used only by the following games: - Far East of Eden Zero - Far East of Eden Zero: Shounen Jump no Shou - Momotarou Densetsu Happy - Super Power League 4 DSP-3 Coprocessor used only by SD Gundam GX DSP-4 Coprocessor used only by Top Gear 3000 ST011 SETA DSP used only by Quick-move Shogi Match with Nidan Rank-holder Morita ST018 SETA RISC CPU used only by Quick-move Shogi Match with Nidan Rank-holder Morita 2 BS-X (Broadcast Satellite) Add-on unit sold only in Japan that played specially-made games that were downloaded via satellite BS-X Flashcart Flash cartridge used by BS-X, as well as some standalone games by Asciisoft Super Gameboy Cartridge passthrough used for playing Gameboy games ------------------------ Unsupported Controllers: ------------------------ Mouse Super Scope Justifier Multitap (4-port and 5-port)
