New WIP up. This one fixes HDMA bus sync timing. I verified this was correct per hardware with the HDMA test sync ROM. It was definitely wrong before. Secret of Mana, Street Racer and Jumbo Ozaki no Hole in One all work. Yes, they worked in the official v030 release, but that release had HDMA sync disabled and rounded. Mecarobot is improved greatly, but still flickers when the golf course is moving. If you're as desperate as I am to play this amazing masterpiece _right now_, you can always hex edit the ROM and change offset 0x1c6f from 0x40 to 0x80 :) I'm still investigating that issue more before I start running hardware tests. I want to rule out things that can't be the cause of the bug first. I've also added (hopefully) proper SPC7110 detection. If anyone wants to test all of them to make sure it works, great. It should give you a popup now saying that it's unsupported. Down to just needing ST-011 detection now. [No archive available] |

bsnes Version: 0.030 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. ------------------ Known Limitations: ------------------ S-CPU - 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 ST-011 SETA DSP used only by Quick-move Shogi Match with Nidan Rank-holder Morita ST-018 SETA RISC CPU used only by Quick-move Shogi Match with Nidan Rank-holder Morita 2 Super Gameboy Cartridge passthrough used for playing Gameboy games ------------------------ Unsupported Controllers: ------------------------ Mouse Super Scope Justifier Multitap (4-port and 5-port)
