Making new games for the Nintendo GBA E-Reader.

I post updates on the games I'm working on, and also little facts/findings on this unique peripheral.

My very first realization that AI was coming was when a coworker insisted Jest had an option it doesn't have. Turns out chatgpt told them...

Oof, I can definitely relate...

This is a cool project. I think it can be adapted for e-reader games too. Playing around with it, it disassembles one of my games just fine. Just need to create an e-reader runtime for it.

My goal is to debut Pixel Pup there and have it for sale. Then have it up on store.retrodotcards.com the next day.

This depends on my printer, who I need to talk to about scheduling the print run. So this isn't 100% just yet.

I'd be honored!

It's still going to be a while before I have physical cards in hand, once I do let's coordinate from there?

Oops, had the wiki entry wrong. Here is the correct link

ereader.miraheze.org/wiki/ERAPI-Z...
ERAPI-Z80 - E-Reader Development
This is the Z80 version of ERAPI. The GBA version is here. Many ERAPI functions use Fixed Point.

It only allows increasing the spacing, not decreasing. So unfortunately it can't be used to bring English text on a Japanese e-reader back to a more reasonable spacing. Ah well.

Been there before, software division can be brutal.

I can't really say, it would take some experimenting to figure out. The e-reader is limited to the GBA's ram, and I believe only 64kb of it at that, so my hunch is this might be doable but it'd be really hard.
