@StonedEdge use the old trick of storing the characters in the Font rom, like old Japanese computers did (MSX/NEC PC88/NEC PC98/Sharp X68000). Of course, the display may not have the resolution, but it would be a neat trick.

@MSP430 so far none of the systems you mentioned go over the resolution of your display. The PlayStation has a few games that go over, like tekken 3, or silent hill in the menus, but I’m sure it’ll look fine on a lower resolution display, if not a tad fuzzy and text might be harder to read in the higher resolutions.
Just know that PlayStation and especially n64 will be iffy on a pi zero. Not sure about a zero 2 for PlayStation, but n64 on a pi4 has many performance issues which is much more powerful than any zero.

@fruitybit That's the first I've see it, I'll check it out.

Thanks for letting me know.

Seems I added Mattel to early, discussing it further over here :

Edit : removed it again see post 9

@mitu Yea tbh I'm not sure what it uses, I just thought I would take a chance incase anyone knew.

@pylades Sadly it's a one-off. Couldn't face doing all that wiring again for any amount of money. It was torture getting everything in there.

@mitu Using the standalone version of MAME, most recent version. And if you run merlin, mmerlin, mbdtower, starwbc you can see this happen.

@cnoto I'm glad you have found a use for it. I had no idea it would help with the pi zero's performance, but I'm happy it does! Thanks for letting me know about it. I thought having an airplane-mode was a crucial feature that was just missing an option in EmulationStation.

@Rion Already saw it. Thanks. We try to keep up on Piboy DMG going's on's. :)

We'll add this as an option in our config.txt.

@Firebird_WS6 thanks for digging into this. I figured there was something but I doubt I would have found it.

@lostless Thanks. I am thinking of cutting an old gba cartridge to fill the space left at the top.

Okay so I figured out what was going on. I had two micro-usb cords, one was connected to my RaspberryPi and one to my laptop. The issue was with my micro-usb to the RaspberryPi, it was powering the Teensy LC but not reading it.

I switched the cords and it started working on the RaspberryPi.

You can imagine how frustrated I was, given I am new to all this.

Thanks for your help Mitu!

This is just an example but you would have to be looking for a controller like this one that would work with what you wantalt text
