Here's something else for a change:
A dump of a korean pirate multi-cart featuring 20 games, mostly NES/Famicom conversions.
I don't know much korean, but I guess the title means something like 'Super 20 Collection'.
They went out of their way to add new sound effects and music to the games (including a very cheesy Super Mario Bros theme remix).
Game doesn't work on emulators yet because there's a custom bankswitching mechanism involved.
Thanks to Svambo for letting me borrow his cartridge!
I've been waiting for a long time to get my hands on that one.
Again thanks to Bramsworth & Azathoth, I was finally able to crack it.
Apart from the usual stupid schemes, it featured a rather obscure protection that didn't kick in before the player fired 32 shots, then waited for another 512 frames before finally crashing the game.
But, as we all know, security by obscurity never works, so here's the crack.
Thanks to eagle-eyed Evan G of snescentral.com, I learned that I was in possession of a still undumped version of Starfox which was never used in retail cartridges, but only in a special cartridge for the Super Famicom Box hotel unit. I had hoped that Nintendo at one point fixed the issues Starfox was having with running on a Super FX in 21Mhz mode, but apparently they never did... The Super Famicom Box version still uses the same old Mario Chip Super FX in 10Mhz mode. No public release this time, as this ROM is only of archival interest, anyway.
Yet again thanks to Lord Azathoth for supplying the cartridge. This game was previously undumped, so I've included both the unaltered dump and a cracked version. Protection-wise, it's still the same stupid crap DVS has been using since Pocket Monsters.
