ROM Hack Interesting stuff in Contra 4...

[enarky]

Wouldn't be suprising if the emulator used in Contra 4 actually is a DS Port of PocketNES. Konami used it before for a few GBA games and loopy said that that's exactly why he made PocketNES public domain. There's a thread about that somewhere buried in the PocketHeaven boards.

 

[OSW]

damn that is teh awesome find. I love to take apart roms all the time these days to see if i can find anything interesting in them, but i hadnt taken the chance to check out contra4 yet.

hilarious that they did this though.

I think it's awesome, as homebrew developers always wanted the paid developers to see thw greatness of homebrew.

Got that a little bit wrong, Konami wasn't involved in using PocketNES (yet?), it's Jaleco, Atlus and Hudson. Pocket Heaven threads here, here, here and here.

This does not (!!!) mean that this is a PocketNES port. I'm just saying it's a possibility. Someone should check that...

Is their nes rom playable on our current emulators?

 

[myuusmeow]

Yep. Opened both just fine in FCE Ultra.

Tank, if you're not busy, could you test Punchout! for me? That game has too many graphic glitches on the NesDS.

EDIT: Arctic_flame from WTF?

 

[Lumstar]

This makes me want to see a 2D Metroid on DS...

Tanks? Wow, another name I've seen before.

Level 2? I can't get past level one!

I'm ashamed of myself

On topic: What games have you guys tried? I know nesDS compatibility is pretty good but are there any games that works on the Contra emulator and not the homebrew?

 

[Tanks]

If I find a compatability list for NESDS, I think I'll write one up for this method. Mind you though that there is no save function and the sound is sub-par.

Just take your time guys and remember the angles where you can shoot and not get hit. Move veryyy slowly

Got up to level 2 boss on hard, can't get any futher.

that's awesome about the emulator discovery. can anyone test if it's the same as one of the homebrews?

 

[ismaboof]

does TMNT 2 the arcade port nes work?

 

[leetdude_007]

I don't see how this is surprising. This just shows that GoodNES have has clean dumps. olé!

 

[Tanks]

So I've started testing roms with the EMU.

Punchout-no
SMB3-yes
wario's woods-no
Puyopuyo-yes
SMWnes (pirate)-no
Double Dragon II-yes
Predator-yes

I've also figured out how to text hack Contra 4 so for fun I've been changing menu names as I've been inserting new roms to test. I've also found out how to display graphics other than the .ANM files. I must say this game is a rom hackers dream!

EDIT

I finally got that friend of mine to help me out with the .SCN files. I was right, they are palette files. I also figured out that the .TS8 files are sprites too. You just need to view them in another codec.

Viewing the submarine boss sprite (a .TS8 file) with a correct palette.

I'll release a how to guide for this eventually. I just want to make sure I've found that this method works for all sprites.

So, any chance to hack the game and get infinite lives? Or invincibility?

you could request cracker to make you a trainer. Of course it depends whether he decides to accept or not.
