Homebrew Injecting roms into VC? With only the web browser? Sure.

duke_srg It says this: "d m c : / d k c . g b c "

(because I tried to load dkc.gbc testing Donkey Kong Country. Had this dumb idea that maybe it was the length of the file, so I chose a file that was only 3 characters before the extension."

Well it is originally 3 characters, but should work up to about 40, however it still on debug phase and I did not test it yet for longer file names, that is why I asked to check load.rom file. So was dkc loaded and is load.rom changed with full Pokemon ROM filename? I will continue to debug code only tomortow, but can troubleshoot bugs now.

dkc.gbc AND pkmnylw.gbc did NOT load.

dkc.gbc AND pkmnylw.gbc did NOT load.

What was the text inside load.rom with Pokemon file as a parameter? OK then, I'll make fixes tomorrow

no luck on nes vc injection. i got my self a copy of a nes vc to test things and all injection has failed. even injecting a TNES rom ripped form another vc still fails. the vc just show black screen on reset or crashes.

Were they the same size? and the addresses have to be correct remember

 

[Codename]

Has anyone had any success injecting any ROMs into Metroid 2?

I have Mega Man 5 512K ROM. I tried inject SMB 64K and SMB3 384K and they failed. but now i went back and tested a 512K nes rom and it worked! need to do more test for smaller roms it seems

I guess they have to be the same size then

 

[Deleted User]

can anyone confirm if For the Frog the Bells Toll work? ( Kaeru no tame ni Kane wa naru with translation Eng. patch applied ) I have donkey kong GB and Metroid 2 to inject into


also, noob question but I read the entire topic, and i'm still not sure. are GB injects permanent? or only the GBC ones via KazoWAR's method?

That's great, NES injector confirmed!

not sure yet but i think you would only beable to inject roms that have the same header has the original rom. i dont know the vc is hard resetting. so its trying to run the new rom with the data it used to init the old rom like mapper number, prg rom size, chr rom size, and if it has extra ram or not.​

If it were the case, it wouldn't crash if we put garbage in the header. It's definetly reading it in one way or another. Could be that it just uses the previous Program Counter which makes it freeze. Even if, in principle we could scour through memory to find and replace those values.

Perhaps the ROMs have to have the same

This is what I figured after posting some source code several pages back.

Quick status update:

1st of all: Thank you KazoWAR for all your work on this!

Now, here's where I stand: I want a way to inject roms and save data(if at all possible). Why? My idea is: since it is temporary, why not make a loader AND backup tool. So:

1: No losing progress in original game.

2. No losing progress in injected game.

So, my plan? Make a "gui". Since there's no way to "scan files"(like a DIR listing in command prompt, for example), we make a predefined list in a text file.
Then, we can, with a selected rom in the list, we can:

1. Inject with save

2. Inject W/O save

3. Backup save to sd

I'm not sure how to get the save though...

Would that be stored in memory like the rom?

it might be stored on the SD Card and then loaded into RAM when you load the VC

If that's the case, we *could* do this, right?

I suppose , just having a GUI is cool enough as it is

 

[KazoWAR]

ok I just injected a header with bad data and the game still boots on reset. so this makes nes injecting very limited.
