Throat Sort sounds like a very... interesting[?] algorithm.

That's not worth the extra overhead in this case.
I'm already dealing with some extremely tight CPU tolerances during certain sections. [CrossPaint's canvas screen, most notably.]
I have PLENTY of space OUTSIDE my fixed bank, so duplicating the driver is not much of a problem.

I unfortunately no longer have enough space in my static 16 KiB PRG bank to hold the driver. To access music data across multiple banks, I must duplicate the driver in each bank :(
If I had enough space in my static bank I could indeed do a proper bankswitch setup without duplicating the driver.

Yeah, LDA #0 would just be more explicit to the reader.
Illegal instruction ANC #0 [Opcode $0B / $2B] clears both the accumulator and the carry flag for free :) I find it quite useful in small ways.

That doesn't sound in any way true.
1. Anything EOR'd with #$00 returns itself. [No bits get flipped.]
2. EOR affects the same status flags as an LDA instruction. [Flags N and Z.] The value result affects those flags.
3. EOR #imm takes the same amount of CPU cycles as LDA #imm. [2 cycles].

I think this is the best case scenario to come out of this situation. Wonderful news!

This news wounds my soul :(
I hope a better solution develops soon. Thank you for all you've done for the NES homebrew scene and others 🙏

I think SNES would be the most logical step forward, but I would also really like to see support for Genesis / Master System.
I think the original NES Screen Tool was the best learning experience I ever had for how NES graphics work, and I think those other systems could really benefit from that.

I sometimes like hearing how my NES tracks sound when switched to PAL without the driver auto-adjusting the tempo and pitch. It often adds quite a bit of melancholy.
Unfortunately, melodic DPCM doesn't pitch down with the rest of the APU channels, so I have to disable the DMC in those instances :(
