Thanks, both patches works fine. Have to check later if there any good games left. I've asked a few years ago in the Magic Engine forum for the possibility to patch CD games via IPS. Nobody seemed interested. Is it harder to patch these games, i mean compared with your Rom patches? There are great games like Dracula X, Spriggan, Gate of Thunder etc.

Jagu called. He said you'll need a FAQ for the Pits of Madness.



http://www.gamefaqs.com/tg16/589017-the-legendary-axe/faqs/5714

I got Legendary Axe going. It took a couple of hours of trying different things. There is code that decreases your energy, and another for when you hit 0. I stopped this so now it rolls back to 99 after 0. This made the energy bar wig out pretty bad. I fixed this. It does it again later in the game but it doesn't prevent the game from being completed at all. I played it all the way through on hardware.

I won't be doing CD games, sorry. Feel free to suggest other PCE games.

Those should all be up now. Let me know. I broke my PC Engine trying a mod to remove jailbars.  :'( Won't be able to test again on hardware until I get a new one in. They should work fine though.

Damn, that sucks. I have the RGB jailbars too, but it's only annoying on some games like Final Match Tennis. I will test you new patches of course.   

edit: All patches looks good so far. But for Cadash there is an US version too, also with a different rom size. The patch for the (J) version doesn't work here.

Cool that is no big deal. How do you get MP in that game? I played it for a little while and didnt see it increase.

Yeah I have a core grafx ii that had jail bars. It was supposed to just be connect a couple of caps to ground. When i booted the system up it flickered and lost power/won't turn back on. I reversed it and the system is still dead. I was pissed.

If you can think of more games you want that's fine.

Only the Mage and Priest characters can use magic in Cadash. More games?

Space Harrier (lifes)
Fushigi no Yume no Alice aka Alice in Wonderdream = (lifes+energy)
Night Creatures (energy)
Operation Wolf (energy)
Street Fighter II Champion Edition (energy)

Thanks for sharing all these patches.  That's an impressive amount of work.

I have one big request though:  Can you go ahead and specify for each game, whether or not the patch is for a rom with a header?  As it is, they're all mix and match, so I have to apply a patch, test it, add or remove a header and then try again.

Sorry I wasn't aware of that. I downloaded a PC Engine Goodset and am pulling roms from it. If you want to make it easier on yourself you could do the same. It is not very large.

New stuff is up. Street Fighter is not a good fit. Both chars use the same code for energy.

Cadash (U) from Goodset doesn't work with Mednafen. Have to use Cadash (usa) instead. It also uses different values for memory.

Edit2: My PCE was brought back to life with a new fuse. Huzzah!

Great, sometimes it's easy like that.  :)

I guess you've patched the most interesting PCE games yet. I've requested some Master System games though.  ;)

Cool. We can do that. I also got in my ToToTEK PS2/PCE converter in so I can use my Namco arcade stick. Shmups are much happier with it.

Looks nice. I wish they would make a Sega Saturn 2 PCE Adapter (Japanese Pad/PAL model 2).

Hehe. Yes, i know this Sega Saturn Style PSX pad. But it's hard to find, mostly very expensive.  :D

Yep. I paid well for mine. Purple is much more common. This is not a bad option also. My RGB mod is from this guy. He does good work.
