dammit ti why must your torture be limitless

> eZ80 has awesome DMA-like instruction that copies byte chunks based on registers and it's nigh-instant to copy 64k it's great
> TI has the opcode disabled outside a 4-byte chunk erroneously unincluded from all blacklists and access regulation
> can't bankswitch and keep registers, and can't write to anywhere but those 4 bytes in that bank
> no reusable code in target bank that i can use via mid-func bankswitch
