Hi there trying to crossflash some GeForce 4 MX cards to work with the Power PC G4 AGP graphics machine i got a stock 128 Rage Pro on it running os9.2 and Tiger 10.4.11, it be nice to get some quartz extreme running ive purchased some cards from gumtree for cheap trying to crossflash on a pc , i have a cha341 eeprom programmer also, tho i find flashing them on a pc is easier as desolder the eeprom flashing it then resoldering its a big royal pain in the A@^, only had partials success with a gain ward card with bga ram but the timmings are a bit off, now to hex edit with the right memory timings , its artifacting , rest of the other cards dont even post, the rom i used was


ive attached the orginal pc rom, wondering if you gurus have some expernice in forth or hexedit to change the rom with the correct timings.
