Hey guys,
I have been playing around with burning eproms and installing them into 4kb game boards using a hex inverter.
I made up a board with a socket on it for testing. I am using a 2732 eprom.
I was successful with writing a few 4kb games like Enduro.
I decided to try Halo 2600. It starts with the title screen but once I hit the fire button it shows the first screen and part of my character. I cannot move and it sounds like the gun is just firing.
I re-read the eprom and it loads fine in my Harmony cart as well is in an emulator. It also compares exactly to the binary file.
I have tried all version inclusing the PAL PAL60 and NTSC versions as I have both PAL and NTSC Ataris.
Unfortunately I only have the one 2732 eprom at the moment so for each test I need to uv erase it.
Anyone got any ideas of what could be going wrong? I have also tried a different 74LS04 hex inverter in case it was that causing the issues but its not.
Attached is a picture I found on here somewhere showing exactly how I have my board setup.
