For the game I'm thinking about, 0.25s might be too annoying, since the transition happens often.

Needing to have a whole set of new tiles ready immediately might also be considered a good use of CNROM. Fortunately, what I did yesterday will help.

At this point, there are two advantages of porting to NROM:

First, it keeps an Action 53 compilation containing the game playable in the latest version of FCEUX for Windows available on the official download page. CHR bank switching in the Action 53 mapper was fixed in r3339, but as of today, the latest version was r3338.

Second, in theory, it saves 512 bytes because each tile that is blank or same-as-previous currently compresses down to one byte.

The interim link will most likely be updated by then, it sounds like.

Today I learned that KrzysioCart is another reason to keep CHR under 8K if it can be under 8K. As a stand-alone CNROM game, it would still work, as it'd be flashed to the CHR ROM chip. But it wouldn't work when incorporated into a multicart, as the CHR RAM on KrzysioCart is only 8K.

Pretty fun. An achievement list somewhere moderately hidden would be nice.

ed: Got powerpak CHRruption on this too.
