It's just not the same. I made games for the PSP and Vita and it's "different" than making games for Windows or Playstation/Xbox. There's something about seeing your creation on a tiny handheld. I guess maybe nowadays we got desensitized to it because our phones are actual supercomputers which can run Fortnite without breaking a sweat, but making a device with 2MB of ram play your game as you imagined it is just hyper cool and (for me personally) is incredibly satisfying.
If you enjoy this sort of thing I’d highly recommend pico-8 and tic-80. Both have pretty full featured dev environments and have a set of restrictions that make developing for them fun.
I'm not trying to be dismissive here - I am the type to be into the nitty gritty nerdy stuff that using Claude skips, BUT I have exactly zero experience developing anything for a legacy hardware platform in any capacity (with or without Claude) so genuinely curious to learn varying perspectives here.
Is it about the idea of the platform having limited capabilities (e.g. akin to Game Bub or MiSTer) or about tactile aesthetics (e.g. possibly vaguely comparable - though not really - to r36t or play.date) or something different entirely.
