Hi guys,
i've made 2 tiny adapters for my repros,
1st for 29F1610 SOP eeprom (16mbits)
2nd for 29L3211 SOP eeprom (32mbits)
While the 16mbits works perfectly, the 32mbits don't boot (always black screen)
Eeproms are set in 8bit mode (/Byte = GND)
The schematic of the 32mb is based on the 16mb, only 2 minor adds/changes, the vcc is connected to an LM1117 regulator and A20(eeprom) goes to A21 snes (8bit mode)
- I've a stable 3,3v on the eeprom (VCC and /WE).
- 2 games tested, lo & hirom, working properly on 29f032.
If anyone have any idea to make it works...
Thanks !
