Ok, starting over. Like you suggested, I'm presuming this is for replacing a 1Mb 28-pin mask rom with a 32-pin EPROM. In which case (and correct me if I'm wrong):
---
UNROM (mapper 2): Bend up pins 1, 2, 24 and 31 Solder pin 2 to hole 22 (A16) Solder pin 24 to GND (OE)
^^^ Also need to tie pins 1, 31, 32 to +5V ???
---
Desolder the PRG chip from the board. · On the EPROM, bend up pin 1, 2, 24, 31, 32. · Solder the EPROM onto the board where the PRG rom was. · Place wire from pin 1 to pin 30, 31, 32 on the EPROM. · Place a wire from pin 2 to hole 24 on the board. <<< This should say hole 22 ??? · Place a wire from pin 16 to pin 24 on the EPROM.
