Updating my Playchoice pcb to the free play vios version 1.1 - what do I need?
I'd like to upgrade the bios on my Playchoice pcb to version 1.1. I burned a copy of Oliver's bios on to a 2764 chip, and it worked fine, but it doesn't play well with 2600's NES cart adapter.
2600 sent me a copy of the v1.1 bios. Do I use the same size chip, a 2764? Or do I need to be using something different? I tried burning the image file to the same 2764 that I used for Oliver's bios and it wouldn't work. I tried erasing the chip and putting Oliver's bios back on - no problem. Erase the chip and put the v1.1 bios on there, and no go.
What gives?
