In working shape: Simply the Best 2001 emulation WIP (part II)
https://m.youtube.com/watch?v=wXZ90_EjU1A
Robbie:
“This is the Work In Progress about the Simply the Best emulation, for MAME.
This game is running in another complex platform of dual Philips processors (SCC68070 for CPU, and SCC66470 for video). This hardware also have a Philips microcontroller S87C751 with internal ROM, RAMDAC to create the palettes dinamically, real time clock, battery backed RAM as NVRAM, 24C04A serial EEPROM with I2C bus, a LTC695CN voltage supervisor to manage the battery drains, a Yamaha YMZ284 sound processor, and finally a huge Altera EPM7128SQC100-10 CPLD, MAX 7000S Family to obfuscate the things in an evil way.
The reverse-enginerring is a real pain, due to hundreds of offsets reading and writting, even out of the ranges.
After a lot of work in team with Grull Osgo, we got the game running the demo/attract, with perfect graphics and colors.”
