[request] RAM Watch - display BCD values #1011

Closed pwolf23 closed 7 years ago

pwolf23 commented 7 years ago

I started TASing with BizHawk and find it to be a superb emulator with great debugging tools. I was wondering if someone could add this feature, as it seems to be not hard to implement:

When adding an address to the "RAM Watch" tool, one has the option to select the "Display Type" of the address as Unsigned/Signed/Hex/Binary/etc.. Since a lot of games seem to save highscores in a BCD format... would it be possible to add a BCD-Display Type?

Example: A game saves your score in 2 Bytes... Displayed Score (in game): 8690 Binary Representation (RAM Watch): 1000 0110 1001 0000 Unsigned Representation (RAM Watch): 34448 I would like to see a BCD representation for the RAM Watch, which would display the actual, displayed score.

Any thoughts on this?

Print your values in whatever format you want using lua. It's there so that everyone could extend the standard behavior, I don't think BCD is a basic need for RAM Watch. Personally, I find lua hud way more handy and only use it instead of RAM Watch.

This is straightforward to add (see our fixed point formats for something exotic) albeit a little annoying, but dont many games use "BCD"-like values pre-adjusted to tile numbers? Already BCD will not be widely used.. with this other consideration, it is even less widely used....

assigned myself, because I started doing this to see how hard it would be

The very first game I checked, SMB, didn't even store BCD in the way I expected. There's no normal way to do this. At the very least, there's 3 ways: Call it TO (tens-ones) or OT (ones-tens) or XO (nothing-ones, what SMB does). There's probably more. I'm closing this as impractical. This would really only be feasible if we added some kind of custom scripted watching capabilities.
