Just researching donor boards more and it seems as if the donor board itself is not what matters. I was trying to figure out the big difference in boards such as TLROM-03, -02, and so on.

From that sheet it appears as if the boards themselves are not what matters most but what chips are on them and what they hold.
Such as a TLROM -03 board containing a MMC3C chip supports Up to 256K of C-ROM and 512K of P-ROM
However a TKROM-10 also contains a MMC3C chip and NES-TKROM-10 and supports 8K battery-backed SRAM, 256K of C-ROM, and 512K of P-ROM.
So one would believe that would be a suitable donor cart as well, it just has save capabilities so you wouldn't want to waste on a game that didn't use save.
I am still a little confused as to the board revisions and what role they play as in TLROM-03, -02, and so on.
In theory it appears the board type is not what matters though is that correct? As long as mapper is correct and the C-Rom and P-Rom have the capacity you need then it should be a suitable donor?
So like Gold Medal challenge is a NES-TKROM-10 so that would be a suitable donor for any TLROM game, but it would be wasting the save capabilities.
I assume in something like Tetris 2 that is NES-TSROM-08 it would require programming differently? Due to the address space remark. Or would that not work for TLROM.
NES-TSROM-[04,06,07]
8K of WRAM mapped in at 6000-7FFF in the CPU's address space. Up to
256K of C-ROM and 512K of P-ROM.
