777 Casino - skip to credits

[andlabs]

777 Casino does have an ending with a staff roll; here are patch codes to start the game at the staff roll (which is written entirely with Chinese characters):

000586:4EF8
000588:64DC

You need them both on simultaneously. These codes should work in all emulators and cheat devices that support PAR-like codes (I used Gens/GS), and it seems to show the male character winning and choosing the money over the girl (or something to that extent; I don't know how the game works). You won't need to worry about the copy protection here. Because these codes replace the beginning of the title screen code with a jump, you will need to disable both codes to get back to the title screen. Enjoy!

I'm still going to post the Super Mario World 64 technical notes; I'll likely do that later tomorrow.

I posted the credits to the game a while back on my channel by playing a physical copy of the game.  Still, thanks for posting this!  It sucks how the ROMs don't work properly; it's actually a pretty good for a gambling game (in that the odds aren't rigged heavily against you) and I'd love to get a working ROM out there, I just don't know why the game doesn't work (if it's copy protection, a bad dump, etc.)

It's copy protection on the Z80 side. I don't know what the trigger is, but it will eventually look for some values in the $40000x region (just like most of the other unlicensed games from that time period) and if the check fails, it blanks a block of RAM (the Z80 can write to 68000 RAM but not read it, apparently — Mamono Hunter Youko requires this behavior to work properly), which will cause the game to crash. I can paste a patch code for that but later as well.

Ah, okay.  A fix patch would be nice so other people can play through the game themselves, as I never showed off the "rewards" in the game.  If it was a bad dump issue I would've been up to providing my cart for a proper dump of the game, but it looks like it's not necessary.  Thanks for the info!

Are the credits in Chinese? If they are, send a screenshot(s) to me and I'll see what I can do about translating them. Thanks.
