At 14,850 games I'm almost done setting up my RG DS.
Of course I have hard drives and data at different locations, but these gaming handhelds can be functional little data caches. I have an RG34XX (looks like a GBA) with a 1tb sd card but this only has a 512gb. The OS on the RG34XX doesn't count the games as far as I know.
Figuring out every system you can run with libretro is a neat way to explore gaming history, as a kid in my area we barely knew the Sega Genesis existed, much less the TurboGrafx 16, PC98, Phillips CDI, 3DO, the Sega CD for example.
I have a few full libraries to add, palmpilot OS games, GamePark32, Java platform Micro edition, some ScummVM maybe, but I'll finish under 17,000 games on this.
I have every gamefaqs txt guide for DS on this, and on my 1tb build I have every game faqs txt guide ever made up to around 2020.
You can find thousands of rom hacks and translations to really preserve some additional obscure titles.
