ESP32 NES

Post by DynaMight » Tue Feb 16, 2021 11:51 am

Built a few things during the most recent lockdown.

I found this interesting code https://github.com/rossumur/esp_8_bit which essentially emulated a NES, SMS & Atari on a ESP32 but allowed composite video output even though the ESP32 has no video out functions except via SPI. I found the Bluetooth controller function a little janky, didnt work with any of my BT controllers but someone added a fork with NES/SNES controller support.

I had originally intended to fit a smallish Lipo battery but space is fairly limited and I didnt want to 3D print a remixed controller bottom so just used MicroUSB to power. I may still end up doing a Lipo as the board ESP32 I used does have a built in charging circuit. Also added a MicroSD slot to store extra roms as the ESP32 only had space for about 4 or so max.

Thank you for posting this I was thinking about doing a GB Pocket build with an ESP32.

Would you mind sharing which ESP32 dev board you used? I see some variants with both LiPo charging and microSD slots which seem like they would be ideal

edit: I was inspired by this guy's project, not sure if he has a thread here !

The board I used was a WEMOS LOLIN32 Lite. Doesn't have an SD slot but easy to add one and there are some with them built in.

I did spend ages looking for a well priced ESP32 with 16MB flash so it could take Odroid Go software but they seem quite few a far between and more expensive. I wanted something cheap ideally and most of the ESP32 handhelds tended to be atleast £30-40. I was very close to buying the Espresso: https://www.tindie.com/products/ampersand/espresso-kit/
