I probably shouldn’t post this, but despite what you may read about After Burner PCBs needing modifications, they are suitable for a 27C040 eprom with zero alterations.

So here’s a game none of us ever played but is worth playing.  And you can jump off the stairs!  A simple rom edit and checksum tweak has me going with infinite lives.

The method we used to use in old C64 days when we needed to do something like that was to clip the leg of the chip with a fine-nosed set of clippers, right tight to the pcb.  Then carefully bend up the leg and solder to that.  No need to cut traces, and if done carefully, it can be reversed if necessary.
