I'm sure you're just throwing in a personal anecdote of interest and already know this, but for readers unfamiliar with these pieces of hardware: The SNES (early 90s) and the GBA (early 2000s), despite roughly similar graphical capabilities, are vastly different machines. The SNES uses a 65816-based architecture running at ~3MHz that's extremely hard to compile C down to while still getting acceptable performance/code size - almost all games for it were coded in assembly language. By comparison, the GBA uses an ARM7-based architecture running at ~33MHz. GCC was available for it literally before it came out. Even though I'd experimented a bit with QBASIC when I was younger, plugging away on the GBA when I was around 14 was how I learned C, how computers really work at a low-level, and roughly speaking, how to "really" code. So this isn't a GBA C++ compiler - that's existed for ages. This is a "just" game engine. It's super cool that people are still working on stuff like this - the GBA is a very fun platform to develop a game on, at a nice sweet spot between straightforward enough to get started on, powerful enough to make something cool, not so powerful that you need a team of dozens to make something impressive (for the platform).
