some ideas and gCore build

[gilmod714]

Fun project to build and tinker with .. I built the gCore fork galaga instead, but I am planning to build this multi-game project also.. once I figure out how to interface the parallel screen to Ada-GFX lib .. ?!

I have added a few ideas , I figured someone could use those ideas in their build:

-used ESP32 wemos lolin32 lite -- it has a battery charging circuit built-in for Li battery
-added Li-ion battery (an old cellphone battery) for portability, lolin32 charges it through USB automatically
-added on/off switch for the Li battery, which acts as a reset also

• used x,y joystick module from an old gamepad controller, added voltage divider
• used TFT 2.4 parallel instead of SPI .. (that's what I had at the time) - modified config files
• used PAM8403 and 1w speaker-scavenged from very old laptop
• added a volume pot to the amp (it was too loud sometimes)
• used the TFT_eSPI lib in parallel mode for iLi9341
• modified config files
• added custom Galaga banner (outside of playing area on top)
  -housed everything in an empty transparent cassette-case for a cool retro feel and I also wanted it to be as small as possible .. parts are very squeezed , but they all fit .. reminded me of "Game&Watch" handhelds :)))

so far , this setup works great , it's almost like a micro-arcade Gameboy wanna be ;)

I had remapped many GPIOs for functionality .. see schematic attached, perhaps it can help someone for a similar build.

Thank you for this cool project .. I will upload more photos when I finish the fab

IN THE MAKING ...

FINISHED AND WORKING :))) === yes, it's ugly .. and I can probably paint the case .. but it's a lot cooler to show the DIY guts and the concept ;)

I will fully-charge and check battery-life .. and see how many play hours I can get ;)

I was able to compile this Galagino multi-game and run it using TFT_eSPI lib parallel setup .. but Digdug always freeze/reset after startup in few seconds ..any ideas why?! .. the rest of the games work fine ;)
