These are great, thanks! That GBA "butano" compiles with -fno-rtti -fno-exceptions, so it is not a C++ engine/library according to C++ standard! It is, however, an impressive piece of work. The ESP32 SDK (I lol'd at your "even", those Xtensa/RISCV chips can even run linux kernel!) is extremely impressive - they support enabling/disabling rtti and exceptions (obviously disabled by default, but the fact they implemented support for that is amazing). So "real C++" is possible on ESP32, which is good to know. For comparision, here are the minimum SQLite dependencies from the submitted article: memcmp() memcpy() memmove() memset() strcmp() strlen() strncmp() Of course you could run javascript and erlang on MCU too, but is that API better than C? Your claim of "skill issue" sounds like RedBull challenge. Please let us unskilled people simply call library functions.
