I was seriously looking into the GameBoy Advance, but the real hardware has gotten quite expensive these days.

I wonder how the latest and greatest Wonderswan is doing in terms of price.

One uses emulator while developing anyways. Try with C64 and VICE and join us at https://csdb.dk/

Yes, but part of the joy is the anticipation of playing on a real device at the end.

Thanks for the invitation! I used a C64 as my only computer in the late 1990s long past its prime, because my mother got a really good deal on a whole set with printer and disk drives and plenty of disks with software (mostly games, from magazines). However, I was still a bit annoyed by the limitations of the system. I guess, if I had had a forth disk, I might have felt different.

In any case, for personal reasons I don't want to explore the C64 more.

But I never had a GameBoy Advance nor a Wonderswan.

Note: Some are slightly pre-1999 (all these, I have at least successfully made a "Hello World" with)

----------------

If they're really wanting 1999, that's the 5th to 6th generation console range with Sega Saturn, PlayStation, Nintendo 64, and Dreamcast. (on these, only recommendations, no successful compiled software)

Playstation is really challenging and remains so even in 2026. Lots of Modchip and disk swap issues on real hardware. Possibilities: https://www.psx.dev/getting-started and https://github.com/Lameguy64/PSn00bSDK

N64 is less horrible, and there's quite a few resources: https://github.com/DragonMinded/libdragon and https://github.com/command-tab/awesome-n64-development

Sega Saturn is still pretty difficult. However, there is: https://github.com/yaul-org/libyaul?tab=readme-ov-file and https://github.com/ReyeMe/SaturnRingLib plus the old development kits from the 90's are still around https://techdocs.exodusemulator.com/Console/SegaSaturn/Softw...

Dreamcast is similar to the Saturn situation, yet strangely, a little better. There's https://github.com/dreamsdk/dreamsdk/releases and https://github.com/KallistiOS/KallistiOS along with the official SDKs that are still around https://www.sega-dreamcast-info-games-preservation.com/en/re...
