GameCube mod for reading burned discs

I've recently gotten into GameCube modding after being into DS and 3DS modding for a few years. I enjoy using as much of the original hardware to get as much feel for the authentic experience as possible. (But I'm open to case modding)

As such, I enjoy using fake cartridges and collecting the games I can and ROM hacking the rest. For a while, I figured there was probably a mod out there that would let me use burned ROM hack discs. I've since discovered the GC modding scene is more about digital roms (which is fine). I've grown curious however as to if it was possible to figure out a way to use burned discs.

Would something like the flippy drive or the pico loader bypass the console's authenticator on ROM discs?

What types of mods would permit as much flexibility for discs and digital roms?

I'm also really curious as to what your guys' favorite mods are.

Bitfunx Memory Card Issue

Hey y'all I've been using my bitfunx memory card for a while now. Recently I've been using two different gamecube consoles more frequently (there hooked up to different different tv's). Went to go play my Mario Sunshine save on the different gamecube and the save is gone. Is the save file tied to the other famecube or is this a save issue?

Issues with Installing PicoLoader

I’m using a SD2SP2. When I originally got the picoloader put in, it booted to Swiss without any issue. Once I put the case back on, it would no longer boot and now it’s sending me to the regular GameCube launcher and then flashing me an error trying to tell me to check the manual. Is the issue my ribbon cable?

NFL Blitz Pro 2027 memory card mod on GameCube

I reverse engineered the GameCube save file format for NFL Blitz Pro. Mapped the full 40-byte player record structure, cracked the checksum algorithm, and built a Python pipeline that rewrites the roster directly in the .GCI memory card file — no disc modification required. This is, of course, a fan-made save file.

On the last post I made, I was still using Madden 2026, but with the new season coming up I decided to update with Madden 2027. I also discovered many extra checks I needed to add to keep the game from crashing. For example, there were some position changes made in the scripts to fill needed slots, like RB to FB and Edge player to LB. And in the modern NFL there are not many true fullbacks, so even more players were added from the real preseason depth chart with some fabricated ratings just to have enough fullbacks. I moved some original punters to Free Agency since there were zero extra that I found on the Madden 2027 player rating page. Also, a few other 2003 players moved to Free Agency for fun.

Audio commentary matching is now on the save files. There were 7 or so players who had exact first-name/last-name matches, like Patrick Surtain II matching his father in the original roster. More details on the GitHub page.

I could use collaborators for non-technical stuff like finishing the skin tone assignments, jersey numbers, and people with different-than-standard equipment like visors. The technical part is solved; I just need some help because about 1,800 players fit into the new roster. You can use the Excel files I have or just type out the changes. And also let me know if it ever crashes. I haven't done extensive play testing.

Definitive GC. Which mods?

I would like to build one „definitive“ Gamecube. I am very experienced with modding consoles (GBA, Switch, SNES,…) but havent worked on a Gamecube yet.
I did some digging, and found these mods were I thought it would make the console „definitive“:
Solderless Picoloader
Bitfunx replacement shell
Now for HDMI I found either a PCB, or „just a cable“ which one should I go with?
Also which usb C for power should I go with? The „cable“ route? Or should I replace the plug?

Like I said, the soldering etc shouldnt be an issue, so even if the mod is more advanced I think I can do it.
Is there any other mods missing?

How can I play my GameCube on a modern TV?

I got my GameCube I currently have a few years ago, and when I first went to play it I had connected it to a flat screen that was about 50 Inches. (If it matters, the first game I booted was LoZ:Windwaker)

I immediately noticed it did not look great, to the point of being borderline unplayable, on that television. After that I would use a smaller sized older TV I had when I wanted to play GameCube games.

I was curious if there was some type of cables, or something I could do to make it so I could play my GameCube on my bedroom TV.

Forgive me if this is a stupid question.

[Homebrew] GCMM-EX v1.0.0 Alpha – a modern GameCube/Wii memory card manager with exFAT support

Hi!

I've been working on a new homebrew project called GCMM-EX, and I've just released the first public alpha.

GCMM-EX is a GameCube memory card manager for GameCube and Wii, built on the proven low-level memory card code from GCMM, but with a completely redesigned interface, navigation model and workflow.

My goal was to make managing real GameCube memory cards feel a bit more modern and straightforward while keeping compatibility with actual hardware.

Some of the current features

  • Backup and restore individual saves
  • Copy and move saves between Slot A and Slot B
  • Batch save deletion
  • GCI backup and GCI / GCS / SAV restore
  • Full memory card backups
  • RAW / GCP / MCI image restore
  • Save banners and animated icons
  • Support for protected saves such as F-Zero GX and Phantasy Star Online
  • GameCube controller, Wii Remote and Classic Controller support
  • SD / SD Gecko / SD2SP2 / USB / GC Loader support
  • FAT12 / FAT16 / FAT32 / exFAT support through libdvm

The UI was rebuilt around task-oriented workflows, with progress screens, confirmations for destructive operations, save previews and easier storage-device selection.

There are builds for both GameCube and Wii.

This is still an alpha, so I'd really appreciate testing and feedback — especially from people using real memory cards and different storage setups.

Download / release:
https://github.com/alexishida/gcmm-ex/releases/tag/V1.0.0_alpha

Source code:
https://github.com/alexishida/gcmm-ex

GCMM-EX reuses important technical code from the original GCMM by suloku, which itself builds on work from dsbomb, justb, Askot and many other contributors. Their work and credits are preserved in the project.

If anyone here gives it a try on real hardware, I'd love to hear what setup you're using and whether you run into any issues.

Screenshots are in the GitHub repository as well.

Thanks!

Picoloader install issues - DOL-001 missing Serial 2 port

I purchased the Mak's tech picloader solderless kit + SD2SP2 pro and attempted installation and ran into 2 issues -

  1. My DOL-001 Gamecube does not have a Serial 2 port. I didn't know this was a thing, so just started the install without checking to ensure that my DOL-001 had the serial 2 port. One I got to the SD2SP2 install portion, obviously couldn't do it. (I did order a GC2SD to try that route)

  2. Out of curiosity, I booted the gamecube with the Picoloader but no SD card. Gamecube boots to normal menu but then an error pops up telling me to check the Gamecube instruction booklet.

Does the second error mean I screwed up the ribbon install or would I get this regardless without a SD card?

I really have yet to find a video showing how to use key to make folds on ribbon. When I installed, I used a video showing the folds but might have creased them too much...or maybe it became unseated putting optical drive in/case? Any help is appreciated I have modded a lot of systems/handhelds but this one is finicky for me.
