Logo of BrMSX.

BrMSX was an MSX emulator for DOS, written by Ricardo Bittencourt. It was first released in 1997, at that time being regarded as the fastest, most accurate MSX emulator.

History

In 1997, MSX emulation was still preliminary. The only MSX emulators available were fMSX and CJS MSX. Neither were very accurate at the time, nor were they fast enough to run all MSX software at full speed, on computers of that era. 1997 (MCMXCVII) was a common year starting on Wednesday of the Gregorian calendar. ... fMSX is a portable MSX emulator written by Marat Fayzullin, one of the pioneers of modern computer emulation. ...

BrMSX aimed to solve these two goals. In order to improve accuracy, the Z80 core was tested using ZEXALL, emulating every aspect of the CPU, down to the undocumented flags. Fast emulation was achieved by coding the emulator entirely in Assembly, and by using a number of hacks, the most successful being a dirty rectangles implementation known as the video cache. The Zilog Z80 is an 8-bit microprocessor designed and manufactured by Zilog from 1976 onwards. ... ZEXALL is part of the YAZE package, the Z80 Exerciser (ZEX) has become the most used tool of emulator writers who want to validade a Z80 implementation. ... An assembly language is a low-level language used in the writing of computer programs. ...

Development of BrMSX started in September of 1997, and the first public release was in November of the same year. The name itself, BrMSX has a double meaning. The Br in the name is an allusion to Brazil, the country where it was coded, but the characters also are the initials of the author, Ricardo Bittencourt. The logo, created by Raul Tabajara, reflects both the MSX imagery (by using a font similar to the logo of the MSX game Aleste) and the Brazilian flag (by using the round shield with the Brazilian sky). The mouse icon used in the GUI was a rendition of the keyboard of Expert (one of the Brazilian MSX models). Allusion is a stylistic device or trope, in which one refers covertly or indirectly Hollys Face. ... Aleste ( Japanese: アレスタ) is the first game in the Aleste Series. ... National flag and ensign. ...

Eventually, interest in BrMSX faded, as fewer people used DOS-compatible systems. The last release was in May of 2000, and included the source code. Source code (commonly just source or code) is any series of statements written in some human-readable computer programming language. ...

A number of features now common in MSX emulation were first seen in BrMSX:

• Z80 core fully compliant with ZEXALL
• Support to MegaRAM
• Support to samples generated by the PSG, PPI, and Konami Majutsushi
• MSX2+ cross-lines animation
• Disk drive emulation through I/O ports
• Dir as Disk, mount directories in the host machine
• ADVRAM, a hardware prototype that was never released commercially
• Interactive debugger
• Multiplayer games (using a serial cable)
• Fast forward button, to skip game introductions
• Save states
• TV emulation (blur filters and scanlines)
• Green monitor emulation
• Emulation of the LEDs (Caps Lock, Kana and the Disk Drive)
