I want to improve performance by adding subroutines callers that use RTS Jump Tables.
I'm using this mechanism in other SNES project and I find it superior to the standard jsr/jsl and rts/rtl combination.
The method described in the link is tailored towards 6502 CPUs; I'm not sure if there might be problems with page boundaries, long/far addresses, etc. I'm still investigating this.
