Having another go at trying some DS flashcarts (actually following a guide for advice this time) and hopefully I can get one that works reliably, unlike the one I currently have. I ordered four different kinds since they're so cheap, to try and raise the odds that at least one turns out to be good.
I wanna play with MoonShell and DSOrganize again and maybe play around with writing a program or two. But I need a flashcart that I don't have to insert a few times in order to do that.
@NovaSquirrel I remember trying to use Tiled for another project and then never using it again, sticking for my own #LevelEditorForDS because Tiled missed the 'push tile to the other layer' or copy-like-you-were-a-CPC that I'm over-using when doing level design with LEDS ^^"
