peekb Posted October 7, 2022 Share Posted October 7, 2022 (edited) With the huge caveat of "I have no idea what I'm doing", I was able to take sage's original idea and build out a simple EPROM emulator using a Teensy 4.1. I open sourced it here: https://github.com/BrianPeek/EPROMEmu Again, and I can't stress this enough, I have no idea what I'm doing. I'm not a hardware guy. But, this hardware, plugged into an old Lynx EPROM cart I had works 100%. I've also used it with a Game Gear and Vectrex EPROM cart, so it's not completely the wrong approach. Adding a wire from the cart's VCC to the power supply of the Teensy allows me to power the Lynx from the USB cable connected to the PC, which is nice. I'll probably add a jumper or something to a future revision. I also ended up adding a quick Reset button to the Lynx so I can quickly upload and reset the console to see the results. Anyway. YMMV, very much a "works for me" project, but thought I'd share since this is where the idea started for me. Thanks!
