Ultra Air Hockey (Sega ports, redux)

Work resumes (again) on the Sega ports of Ultra Air Hockey    As I may have mentioned earlier in older news posts, the BEX/Sega homebrew port of Ultra Air Hockey was cancelled around Winter 2014/2015. (BEX is a BASIC language for the Sega Genesis/CD/32x.) This was due to several issues that occurred while developing it, including instability of the BEX compiler and other bottlenecks. As the homebrew ROM executable became bigger, internal errors of the compiler being unable to compute jump offsets of large "bsr.w"...
