Hi,
ive tried to create a cartridge of D+PadHero (www.dpadhero.com). I have used Kirbys Advanture as donor cart and used two 256kb EPROMS (27C2001). I have followed the instructions given on the nesdev page.
The following things i have done:
- Unsoldered the Maskroms
PRG Rom:
- Bended up Pins 1, 2, 24, 30, 31
- Soldered remaining Pins on the Board
- Connected Pin 2 with Hole 24
- Connected Pin 24 with Hole 16
- Connected Pin 30 with Hole 1
(the conversion on nesdev says to connect pin 31 with Hole 2, but the 27C2001 doesnt have an A18 line (but it tried connecting it also, but didnt work either, so i removed it again))
CHR Rom:
- Bended up Pins 1, 2, 22, 24, 30, 31
- Soldered remaining Pins on the Board
- Connected Pin 2 with Hole 24
- Connected Pin 22 with Hole 31
- Connected Pin 24 with Hole 2
- Connected Pin 30 with Hole 1
What have I done wrong? all i get is a blank grey screen. Please help.
Thanks
