The nes emulator in 3050a/3051a must be exclusive for the chip (remenber is a ARM CPU class) in some model run slow in other in 100%, the roms maps are not all compatibles (is similar to nesticle nes emulator for DOS).
In upgrade firmware option inside menu is the key for enter to pmp hardware/software, is need get:
*SUNPLUS 3050A especs...
*Memory space...(Hex)
*Languaje (probably C...or ASM for that CPU)
In PMP there is almost the next code:
*Codecs
*Emulator
*Viewer
*Player
The "OS" size probably is around 2/4Megabytes (or more!)...sorry for my english...i'm from venezuela!
