Homebrew Project [RELEASE] FriishProduce - multiplatform WAD injector

CatmanFan · Apr 30, 2023

Today I am rising out of the dead to announce a new project I've been working on for about a month now: introducing FriishProduce.

What is this?

FriishProduce is an automated WAD injector which allows for ROM/SWF replacement and customization in certain Wii VC channels. What's unique about it compared to other injectors? By handling many steps directly from the program's code, it bypasses several third-party assets & apps which may otherwise be required in Wii VC injection (such as Wii Common Key, and most of HowardC's tools). Some examples:

Automatic WAD/U8 handling using libWiiSharp or Wii.cs
VC ROM injection through hex writing and/or file replacement - bye-bye AutoInjectuwad
Automatic banner/icon editing using VCBrlyt
Generates custom savedata image using original WAD's source TPL/WTE(s) - good riddance VCIconGen
Automatically edits savedata title using hex or .txt writing - Sayonara VCSaveInject
Additional content/emulator options for each platform where supported
Replace WAD contents with forwarder to auto-load specific emulator core and ROM

This was actually based off of an earlier project that I worked on back in 2020, until it was left abandoned and eventually wiped after my hard drive failed. I started work on a preliminary revision of FriishProduce for around three weeks before my then-seven-month-old drive also ended up failing, after which I coded the current version in about a week or so.

See the Wiki for a more detailed explanation on setup & usage. TL;DR:
1. Select a target platform, then browse for a ROM, and select a base WAD.
  - Optionally, you can also browse for a *.bps/*.ips to be patched to the ROM before injection.
2. (Optional) Toggle the "Customize" checkbox, then fill in the relevant fields with the game's title, a shortened version thereof if needed, its release year and the number of players.
  - An image of the title screen is also recommended, but may not be needed if you are injecting a non-cosmetic ROM hack (e.g. a randomizer, TAS hack, etc.). Left click on the image field to browse for a new file, and right/middle click to remove it.
3. Enter a title ID and change any content options to your liking.
4. Save the WAD and you're done!

Aaand already I have just released a new version (beta v0.11). Mostly bugfixes for now:

Some issues affecting compatibility with Japanese/Korean WADs
Language selection may not work correctly if list is not alphabetically ordered
Changed bitmap generation of TPL savedata to using new bitmap instead of loading from the original imagefile directly. This prevents any errors claiming that an image file is in use by another process
General system stability improvements to enhance the user's experience

Of course, I may not have checked fully for all potential bugs, so anyone is welcome to approach me on any that I may have missed. Lol

Sounds VERY nice if this aims to be the ultimate and most featured WAD injection tool.

Disorarara · May 14, 2023

Is there any way you can add F-Zero X to the list of supported wads? This injection tool is amazing!

Hello, it should be included in the list now following the latest release (v0.20). Thanks!

RunningSnakes · May 25, 2023

Awesome! Simply Awesome!!!

WAD Injection couldn't be any easier. This tool would have saved me weeks of time 10 years ago, injecting 250-300 games the old fashioned way.

@CatmanFan

I have a few questions...

1. Are there plans on adding more base wads, or is there no need? I'm mainly concerned about SNES Super Metroid. It seems i used SM as a base as often as DKC2.

2. Are there plans on adding injection support for TG16/CD, NEO, MSX, C64, Arcade?

3. Why so many base wads for N64? I never injected N64 so forgive my ignorance if they all serve a specific purpose.

Anyhow, i'd like to say congrats and thanks for this beautiful work.

Nintendo 64 VC used a unique emulator for every single game, so it's worth trying every single base wad until you come across something that perhaps might work.

1. Depends on the specific console, some will likely only need one or two base WADs at least. Interesting that you mentioned Super Metroid, because up until now I only considered bases with the maximum ROM size available to fit most games. If that is an option to be looked into, then I may consider also adding it to the list

2. Neo-Geo, TG-CD and C64 require additional tools (Custom Frodo, CDRWin or DAEMON Tools Lite, ...), so it's going to be significantly harder to get them to an automated process. For TG-16 HuCard and MSX it is only a matter of replacing the ROM & savedata files in the 00000005.app contents folder. As for Arcade, I'm not sure exactly how the injection process works yet and so haven't considered any plans for including it. The most immediate plans would be on getting TG-16 & C64 support implemented in the near future.

3. As Disorarara mentioned there are many different emulators for each game released (later revisions use a compressed ROM format instead of storing it raw). Some games may work on certain WADs but have graphical or audio issues in others.

Thanks in advance!

@CatmanFan same issue here.
Also, could you also support FCEUX TX/Snes9x TX/Not64/my mod of Wii64 1.3?

On this thread i have documented the meta.xml arguments of almost every argument-supported emulator i've messed up with: https://gbatemp.net/threads/my-coll...-for-some-best-wii-homebrew-emulators.591509/

Besides that, great job with this simple tool, also i'm positive this can make complete VC channels and Single ROM Loaders!

Crap, must be something with how the app handles platform-specific options, and I forgot to implement a failsafe there. Should be fixed on Github now.

Try replacing the FriishProduce.exe with this one and see if it works

Neo-Geo

@CatmanFan
I sent you some documentation of NeoGeo VC romset handling and structure that @sr_corsario sent me time ago, for the first NeoGeo VC game bases which uses a simple game.bin ROM file, before Nintendo moved at game.bin.z (which i made a improved tool for make/injecting custom game.bin.z too)

I sent you that documentation on my Discord server.

Works like a charm! Fantastic work, this is the easiest tool for injecting N64 games ever

Is it possible to add Pokemon Snap as a base wad in the next release?

Also somewhat related but does anyone know why audio is broken on some N64 injections? I have tried wetrix, mace the dark age and ISS 64 and the audio is broken on NTSC but if you force PAL speed at 50hz the audio is correct - I wouldn't mind it but the speed is slower!

EDIT 2: I figured it out - Wetrix with Mario Party 2 will render proper sound on NTSC as well as run the game at correct speed - super important as F-Zero X would run the game just a tad too fast which lead to more unnecessarily difficult gameplay

Mace the dark age will run with ~~Ocarina of Time~~ Star Fox 64 with proper sound on NTSC

It's so easy to mass test each base wad now with how fast this tool works!

steval_beaning · May 27, 2023

would there be a way to apply gameshark codes to injected roms? i say this because pilotwings 64 works almost perfectly when injected, aside from the infamous shadow bug. project64 elects to fix this by applying a gameshark code, so if there were some way to apply this code to an injected WAD or to convert it to a gecko code, then this game would work perfectly, which would be useful since both Wii64 and Not64 struggle with it iirc.

The way I look at it, there's two options here

1) That gameshark would need to be converted into an ocarina code for your wad injection - that way you just apply the ocarina code using a loader like triiforce or

2) You directly inject the gameshark into the rom before injection using this tool:
https://www.romhacking.net/utilities/1659/

And then inject that rom into the wad - I have no idea how viable this is but I'm testing pilotwings right now with sin and punishment with my patched rom and hopefully it will work and run

EDIT: No success, just crash on classic controller screen. I had a similar issue trying to inject a patched Mace the dark age rom which normally works fine with most wads so maybe virtual console just doesn't like it when codes are patched direct to rom - try it out for yourself and see if you have any more success

I'm trying hard to add it with my friend @CatmanFan, i made a PR to GitHub, hope it gets taken care.

yeah I didn't have any success with patching gameshark into the rom - converting the code to gecko might be viable but I've no clue how you'd do it

My patched roms didn't work either in wad injection or not64, there's a thread on gc-forever talking about this too

https://www.gc-forever.com/forums/viewtopic.php?t=4657

It seems the general takeaway is that injecting codes for WAD usage has an extremely low chance of working due to how the virtual console emulator hates injected code, and a higher but still low chance of working on Not64 or Wii64 rice, though I see Wii64 apparently did at one point have a gamehack for pilotwings 64 to remove the black box so that might be worth investigating further
