Does GBStudio run on Android? Because I only have a modest tablet from 2016!
Nope, I'm afraid it doesn't. It's either windows, mac, linux or btfo
With a tablet from 2016... Go for javascript and phaser for instance
https://phaser.io/download/phaserce but that's web browser games, not roms for GB or anything else
You also have godot that runs on android
https://godotengine.org/download/android/ for native games, but again fugget'about making roms with that.
Nah, you need a PC, and to make GB roms or megadrive roms (with SGDK) you don't need a big config at all, just a PC config... Which a 2016 tablet running on android, isn't and never has been.
And you'll need a fucken keyboard get used to it.
That being said, you can easily run GBstudio on such device "Firebat T8 Pro plus"

At $123.30.
I ordered one with the N100 processor, 16GB of RAM and 512GB ssd disk a couple of months ago for my mom, I ditched windows and installed linux Mint cinnamon on it, of course (100% compatible, no install problem, no missing driver). Runs pretty well for everything such as web browsing and streaming, GBStudio runs flawlessly on it, GIMP also works fine, I guess Krita will do also, probably blender too but don't expect to go beyond the realm of lowpoly renders typically, pretty much everything you need for 2D game deving with SGDK or GBStudio will work fine as long as you set a reasonable screen resolution of course, (1920x1080 here, on a 27" monitor). And it's noiseless btw, you won't hear the cooling fans.
For 100 bucks you can have a descent monitor
https://www.aliexpress.com/w/wholesale-Gaming-Monitor,-1080P.html?spm=a2g0o.best.search.0 you can also have one for much less if you buy a second-hand one (don't forget to take one with speakers or buy speakers seperately, or settle for earphones...)
So yeah, $223.30... And of course, you'll need this
https://www.aliexpress.com/item/1005008721177581.html Wireless Keyboard Mouse, $16.08.
So that's $240.
You get a similar config with a smaller screen with that laptop but then IDK about linux compatibility
https://www.aliexpress.com/item/1005006753588833.html for $187.73
For a $50 difference I take the desktop config over the laptop. Because we're talking about spending hours typing, doing graphics, deving, watching tutos on youtube... Not just scrolling on tiktok. It's possible on the laptop also, but it's more comfortable on a bigger screen and a real keyboard that aren't soldered to each others. Also, linux compatibility.
Now again you can have it for half the price if you go for second hand products, but well, I wouldn't do that except for the monitor eventually.
