{{#seo: |title= (Computer) - GameBrew |title_mode=append |image=msxadvance2.png |image_alt=MSXAdvance }} MSXAdvance is a MSX1 emulator for the Gameboy Advance. It was originally a quick and dirty hack of his ColecoVision emulator [[Cologne GBA]] since both systems have a Z80 CPU and the same VDP. ==Features== *A lot of games can actually be played. ==Installation== '''Note:''' You must supply a BIOS to be able to run games. A freely available Bios can be found at [http://cbios.sourceforge.net/ here]. Run MSXAdvance.exe to add roms to the emulator. Use the Bios tick box to add a BIOS. ==User guide== ===Settings=== Controller (settings for controller): *Controller - 1P=Joystick1, 2P=Joystick2, Cursor=Keyboard cursor keys. *Remapping - Use joypad to select key and press A to confirm. Display (settings for the display): *Unscaled mode - L & R buttons scroll the screen up and down. *Scaling modes: **Hard - Every 6th scanline is skipped. **Normal - Every 5th & 6th scanline is blended equally. **Soft - All lines are blended differently (experimental). **Scaled modes - Press L+SELECT to change which lines are skipped/blended. Other (misc settings): *Speed modes - L+START switches between throttled/unthrottled/slomo mode. *Sleep - START+SELECT wakes up from sleep mode (activated from menu or 5/10/30 minutes of inactivity). ===Advanced=== EWRAM speed: *This changes the waitstate on EWRAM between 2 and 1. *This can probably damage your GBA and definitly uses more power, around 10% speedgain. Use at your own risk. Link transfer: *Send a MSX game to another GBA. * The other GBA must be in multiboot receive mode (no cartridge inserted, powered on and waiting with the "GAME BOY" logo displayed). *Only one game can be sent at a time, and only if it's small enough to send (approx. 128kB or less). *A game can only be sent to 1 (one) Gameboy at a time, disconnect all other gameboys during transfer. *Note: Use an original Nintendo cable. [[PogoShell GBA|PogoShell]]: *Add an empty file and a BIOS. *Copy msx.gba to the plugin folder, rename it to msxadvance.mb (or compress it to .mbz). *Then add wither one of the following line to the pogo.cfg file: **<code>rom 1 msxadvance.mb 2</code> **<code>rom 1 msxadvance.mbz 2</code> ==Controls== '''Menu:''' Up/Down - Select game A/B - Start selected game '''In game:''' L+R - Open the menu A - Choose B or L+R - Cancel '''MSX 1:''' D-Pad - Joystick A/B - Fire L - 0 R - 1 Start - 2 Select - 3 R+Start - Bring up Keyboard ==Screenshots== https://dlhb.gamebrew.org/gbahomebrews/msxadvance3.png https://dlhb.gamebrew.org/gbahomebrews/msxadvance4.png https://dlhb.gamebrew.org/gbahomebrews/msxadvance5.png https://dlhb.gamebrew.org/gbahomebrews/msxadvance6.png ==Known issues== Missing: *Not all keys are mapped to the GBA. *Correct sprite collision and overflow. *Screen mode 3. *Savestates. Bugs: *Screen mode 1 is not correct. *The sound is not great. ==Changelog== '''V0.4 2009/04/08''' *Fixed timing of HALT instruction. *Optimised all Z80 memory reads, one instruction and cycle shorter. *Optimised DEC opcodes. *Optimised SBC A/HL opcode. *Optimised CPI, CPD, CPIR & CPDR opcodes. '''V0.3 2007/12/03''' *Added 64kB of RAM instead of 32kB. *Fixed initialization of horizontal position of keyboard. *Fixed initializing of all CPU regs on reset. *Fixed pushing and poping of AF register (BC Quest for Tires II). *Optimised some of the SBC instructions. *Optimised DAA opcode. *Optimised one of the SRA opcodes. *Optimised tile rendering. '''V0.2 2006/04/30''' *Added a virtual keyboard. *Added better keymapping. *Added SCC sound emulation. *Added 32kB RAM instead of 16kB. *Fixed Multiboot transfer. *Fixed blending when used as plugin. *Better update timing in PAL mode. *Better game mapper detection.
