I'm working with Arduino IDE 2.3.3 on Windows 10 and using the esp32 v2.0.9 board package by Espressif. The microcontroller I'm using is a "ESP32 WROOM-32 Development Board TYPE-C CH340C" that I got from AliExpress. Within the IDE, I chose the ESP32-WROOM-DA Module on Com19 because it's the only board that had WROOOM in it's title.

I'm a noob at Arduino programming but have accomplished a lot with addressable LED's, switches, motors, etc. using quite a few different microcontrollers. I followed your steps, downloaded the proper ROM's, ran the conv_win.sh script, and added the Z80-081707.zip library to the IDE.

Upon opening galagino.ino and choosing "Upload", I get the following set of errors, all related to 'StepZ80'. I also tried extracting Z80-081707.zip directly into galagino-main -> galagino and I get the same errors:

Can you please recommend a solution? It's probably something really simple that I overlooked. Thank you for such an awesome project! I designed a 3D printed handheld case in SolidWorks and have all the parts ready to go - can't wait to get my Galaga on!

The python script patches the z80. You need to run the python after installing the z80 code.

Thank you for such a fast response! I will do that now. I will post my build along with my SolidWorks + STL files once everything checks out and my build is completed.
