New BS Zelda Map 2 Episode 3 ROM dump

Hey guys, I know it's been AEONS since I last posted, so hopefully this is big enough to be considered worth posting about.

Over at no-intro, skaman sent me the 8M pack dumps of sanmaiwashi. One of them is DEFINITELY to your interest here;

Assuming all checks out, this is a pure 8M dump of BS Zelda Map 2, episode [strike]3[/strike].
(EDIT: I was told it was episode 3, but it appears to be episode 1 on closer inspection. Anything further here that would be episode 3-specific is now moot, but thankfully that isn't too much.)

I consider this a bit of a milestone considering we spent so long with an impure Map 2 ROM.
1) We finally have a 8M Pack ROM dump of one of each BS Zelda broadcast.
2) With this, we can possibly un-do the "impurities" of the previous dump and properly restore the original dump state.
3) I did a quick check using cheats - Besides the expected blue manhandla and blue gohma, the "extra polish" Map 2 has is in this ROM, so it's safe to assume it was there from the start and not just added for episode 4, which gives credence to the possibility that the previous ROM is indeed episode 1, something which I recall some ROM scenes internally debating.
4) It is possible to use the complete "pure" template to:
a: Quickly make the other Map 2 episode's ROMs (As in, ones that would be similar to what was actually downloaded to a 8M)
b: Make a theoretical "Polished Map 1" broadcast by putting the Map 1 data in Map 2 and doing similar

Of course, this is mostly just ideas. For the time being, the pure ROM in and of itself is great to have. I hope you guys take the time to check it out! It will be worth comparing/contrasting to previous dumps, although considering I was able to use the exact Map 1 cheats like previously this should be a very similar ROM to those.

EDIT: I did a hex compare using Fhred.

Hi Kiddo, was a while. Before I say anything else, I am finished with hacking bszelda.

I also do not like to diminish your enthusiasm about the rom, but making a hex comparison with the swc we offer at the page, I checked every address:

upload pictures

Most addresses of our "impure rom" simply rewrites bs-x bios registers so that the emulator is able to boot is, like LDA $115808 -> LDA $701808. Your rom crashes on normal emulators, as these bs-x registers (bank $11) are not remapped to bank $70 (sram register).

Other changes:
a9 12 8f f9ff 7f a9 07 8f ff ff 7f... changes the timer to 18:07 so that the game doesn't freeze immediately.

Then I found a small change in the ingame header
guess this implements a srm.

It is the very same rom (map2, weekX) as we provide! except that our version is "impurified" to boot on emulator

Thanks for explaining what the changes to the ROM were.

Also, don't worry, my enthusiasm is as a ROM preservationist. The impure ROM just wouldn't do. I understand you may not feel this is that big a deal, but proper archival of Satellaview data is critical.

And we've come a long way in emulating these, by the way.
I can run the pure, untampered ROM in LuigiBlood's snes9x-sx2 like this. It can also run on a sd2snes this way.

Maybe someday I can do the same with the Sekiban ROMs ... though the PSRAM work would be quite the feat.

That's awesome news actually! This confirms the old impure dump we've been using is not corrupted and don't require fixes. Great find Kiddo and great investigation work Conn!

I think the best approach here is to distribute it as an alternate download, just like we did with the Map 1 SWC ROM, and credit the source.

Not really related but I thought I'd toss this in here in case of possible interest:

It's not a particularly great sprite edit but I thought you guys might be inspired by it. (inb4 Master Quest now has weapon endurance. *shiver!* )
