Added Tatsujin invincible. Did this manually because I couldn't find codes for it.

No problems with Tatsujin, only the music stops after any hit. Not big deal though, not the best music ever.

Yeah the music stopping annoys me as well. I'll try to hunt it down on the games it happens on. It is a random value so it needs trial and error to find it.

Gradius was fine. Jigoku Meguri though isn't completable with the invincible patch. You have to die at the final boss and turn into a dragon. Otherwise you can't beat him. Anyway, should be possible with infinite lifes maybe.

Added Paranoia invincible. Found this one manually as well because no codes. Walls will still get you.

Paranoia looks good. You had luck with Gradius, maybe Parodius works then too.

Added Parodius invincible no music

Gradius was cool because the ship and stop music code was right next to the death code. I wish the others were like that. Gomola Speed is what is giving me grief for whatever reason.

Added Parodius invincible no music

And you can't collect the extras/weapons. There is a "special" game mode in the options, then the music still works if you get hit. Though you can't collect the extras neither.

How about Raiden?  ;)

Added Raiden invincible no weapons which seems especially terrible. I need to teach you how to poke at this stuff so you can hunt with me.

Hehe, i suck in these things. That's why i'm glad that you can do the patches. A shame that there is no cheat device for PC-Engine ram cheats.  :D

Yeah, that was kind of the appeal. I like cheat codes but I don't like to play games on emulators. It was also a system I had when I was younger but haven't played in a long time so most of the games are new to me.

I spent two hours trying to find the music code for Kyuukyoku Tiger. I fixed the blades stop spinning after death, which makes it better looking. I also went to read on gamehacking.org about keeping powerups. VisitntX has a reply on the PCE patching thread where he just kind of says that is the way it is. If he wasn't willing to fix those then I am probably in over my head.

I'm going to back off the invincible stuff and just worry about infinite lives. If you want another invincible check this thread:
http://gamehacking.org/vb/threads/2642-VisitntX-s-PC-Engine-Cheats

If there is a game that has a code beginning in 1F I should be able to do it. It just seems like these lead to unexpected side effects - no music, no powerups, game can't be completed. I merged everything back into the pcecheat.zip. I also added my incomplete Bloody Wolf. This game is annoying to patch. I have it to where bullets and people colliding with you don't do damage.

It's fine, you did enough invincible patches for me. Bloody Wolf was on me infinite Energy List anyway, since it has hitpoints. As you said, probably easy enough to patch like infinite lifes.  :)

Infinite Energy request list:

Energy bars or more than one hit points
--------------------------------------------------

Mr. Heli
New Adventure Island
Bikkuriman World (J) [T+Eng1.00_DemiForce]
Bloody Wolf
Override
Ninja Spirit (Arcade is one-hit, PC-Engine Mode 5 hits)
Magical Chase (U)
Dragon's Curse

Added all of those ;)

Bikkuriman World (J) [T+Eng1.00_DemiForce] - This game stores energy in some really weird way. I spent forever trying to figure it out. I made it infinite potions which refills your health when it runs out.
Bloody Wolf - Can still die with some bosses
Dragon's Curse
Magical Chase (U) - Identical to J
Mr. Heli - Walls can still kill you. Combine with infinite lives
New Adventure Island - This should probably be invincible
Ninja Spirit (Arcade is one-hit, PC-Engine Mode 5 hits) - Uses same code for both
Override

Edit - Added New Adventure Island invincible. Please try this one out. Took me a good while to get

Great stuff, Kyle. I will try all patches soon. Many thanks, once again.  :D

edit: Looks pretty good so far. Two things:

1. Could you please add the "keep weapons" stuff to Dragon Saber, or that you can keep at least the 3 dragon heads/different dragon forms after a hit? Just like for Dragon Spirit
2. The Legendary Axe patch for Infinite Energy works fine, but as expected the bonus counter at the end of any level never stops. It's Ok.

edit2: Infinite Energy for Blue Blink/Aoi Blink (t+eng) would be nice.  :)
