My first post over here, don't be harsh
Well, I guess we all know the RG300 has, say, a nonstandar battery. But Nokia BL-5Cs are quite standard and cheap, and their contacts match those of the RG300 battery connector. But those are way smaller than the provided battery.
So I 3D printed an adapter shaped like a scaled up version of an SD card to put the BL-5C battery inside and power the RG300 with it...
I even printed a funny sticker; my 2D printer wouldn't cooperate, it was intended to be orange but it looks radioactive. Funny because of the Nisu brand (bootleg branding, "ni su madre los conoce
" like "not even their mother knows about them
"). Anyway, I could have cut it from EVA foam, even cardboard, but those options gave me the creeps. Maybe someone around here will just do that. I tried several models and settings, I ended up removing the clip piece so it's just a tight fit kept in place by the... springyness... is that a word? Not a native English speaker, sorry. Well, the pressure of the contacts in the RG300 against those in the battery keep this thing in place just nicely. And the angle cutout has a slope to take it out using a fingetip. Oh, I had to make two recessed slots for the battery lid. That's... mostly it.
If anyone wants the size of each part or the 3D printer config, just drop me a line. I'm really not into Thingiverse, but if anyone wants the STL file I can share it too, we'll find a way.
And while we're at it, does anyone know how to use pixel-perfect 2x scaling in any GBA emulator (RG300)?
I got the IPS screen, it's indeed 480x320 and all I want is sharp, big pixels for my GBA games.
