Given that the only existing commercial PS1 emulator for 2600 frame-skips (Activision Classics) and that's on a 33mhz 32-bit machine, and given that the first time I saw a 2600 emulator run at full speed was on a 486DX100, I'd say it's got to be impossible to reach 60fps on a GBA 2600 emulation without somehow porting the games over one by one.

Oh god you are correct. The main issue is that the 2600 uses a 1.1Mhz 6507
CPU. The GBA is a 16Mhz ARM7 CPU. This my default means that you have only
16 cycles to emulate each and every 6502 instruction. That leaves almost NO
CPU time left to emulate the audio, video or input routines.

There are techniques to "cheat", but this is NOT a trivial task. Anyone who
thinks this can be done in a simple manner is deluding themselves.
