The project page goes over the improvements to power delivery and audio output, so not sure what else you're referencing here. Also remember that the AGB's audio is pretty garbage for what it should theoretically be capable of; it certainly doesn't have an SNES-level (edit: sound capability). Zekfoo has done quite a bit here to maximize its potential, and the results are far better than the piling on of many additional capacitors that other modders have experimented with to mixed results. Ultimately, nobody's stopping anyone from playing AGB carts in a DS if that's what you want to do. (Don't look up "Game Boy Macro" mods.)
