Thanks for the info, thefox.

An additional thing that source might help is to be able to send you additions/patches for PowerMappers. We're already in kind of a horrible situation where a lot of people have 3 layers of mappers installed on top of each other, I'd hate to be creating yet another mapper repository overlay. :S (Of course... this particular problem could be better solved by bunnyboy.)

Put in a bit above you, did you miss it?

Or, if someone got the ones that I tinkered with Loopy's code to make, 4. Even if he built them; I never got around to getting that Xilinx license. Then again, those are [so far] strictly disjoint from mappers that others implemented.

In any case, I've got a spreadsheet with who's made what mappers for PowerPak. Haven't managed to automate its color-coding yet, though.

If you've got info on other mapper sets maybe add it to the wiki under and "other mappers" heading?

It's just a compilation of the information on that page and my own mappers, so it's not new information. The information I was trying to direct you to was the loader disassembly.

…besides, not all of the mappers in my pack are In Working Order; I was intending to wait until they were before adding my own to it. But I suppose I can add it in.

I can fill in a couple of details about the loader:

Quote:
;this is odd, as loader.asm's LoadWRAM consists of a lone RTS instruction

The LoadWRAM routine from firmware was probably patched out as being buggy at some point (and replaced with the same thing handled in the menu modules).

Quote:
return: RTS ;this is at 046C. Why they don't just RTS at $0404 I don't know.

IIRC, the firmware modifies the opcode at $404 to an RTS temporarily in some cases and then restores it to a JMP. So if you have a non-JMP opcode in there it will become invalid when it's "restored".

Quote:
I see a bug in the PowerPak firmware in LoadPrgChrSize. It assumes power-of-2 sizes for bank counts, as it subtracts one and uses that as its address line masks.

This depends on your point of view. ROMs with non-power-of-2 sizes are often considered invalid, anyways. It would make some sense for CHR, but we haven't standardized on how to map such sizes to the address space (quite many options here).

Yeah, the situation is not great, but I also don't have the time or motivation to become an active maintainer of the mappers.

...

I guess I might as well post the ca65fied firmware function and variable definitions:

Thanks for the info, thefox.

An additional thing that source might help is to be able to send you additions/patches for PowerMappers. We're already in kind of a horrible situation where a lot of people have 3 layers of mappers installed on top of each other, I'd hate to be creating yet another mapper repository overlay. :S (Of course... this particular problem could be better solved by bunnyboy.)


My preferred recipe has four layers plus : official, beta, loopy, power, then a few cherry picked individual ones, including from the save state mappers :

Perhaps we should take general discussion of using and creating PowerPak mappers out of the topic about thefox's particular set?

edit: Also, Loopy already seems to have included an NSF player in with his mapper pack.

Hey silly question here, but where do we put the slot files? Do they go into the directory with the ROMs?

You can put them anywhere you want.

Right now they're in a root directory called SLOTS but I don't seem to have the ability to save with them. The option isn't available. Am I missing something?

Do you mean "the save-/loadstate options are greyed out"? then…

You have to pick your slot file from the menu after you pick your ROM, before you boot the game. Unlike the built-in SRAM chooser, the [game-genie-code-entry] screen will not update to reflect that you have chosen one and display its name.

If you mean "the menu does not offer me the chance to save after I hold RESET (as one would using the pack-in SRAM saver)" then I suggest saving a state before you quit, and using that to hold your progress.

Aha. That makes sense then. I found it...wasn't looking. My bad.
