Z-GX by cheloruiz79 https://github.com/hotker79/Z-GX Forked from and based on the great foundation of Seta GX (project still active), by fadedled https://github.com/fadedled/seta-gx Controller support: Gamecube controller. Wiimote. Wii Classic Controller. (there is a bug currently where the directional Down is always pressed). (Fixed in build 20260801) Wii U Pro Controller. (there is a bug currently where the directional Down is always pressed) (Fixed in build 20260801) Notes for Z-GX: App folder: root://apps/ZGX/ Covers folder: root://ZGX/art 128x192 PNG with the same exact name as your game file. BIOS folder: root://ZGX/bios/bios.bin Games folder: root://ZGX/games Games can be CHD or CUE+BIN, the latter is the most compatible, some games do not work on CHD yet. Backup RAM folder: root://ZGX/saves - Since build 20260803B and onwards, 240p mode is enabled by pressing Z+Y (Gamecube controller) / ZL+ZR (Wii Classic Controller / Wii U Pro Controller) on the emulator menu. This will create an empty 240p.txt file inside root://ZGX. It will delete it again when you disable it. Reload the emulator to save the setting and activate it on next boot. - The 4M RAM cartridge is always OFF at boot. Enable it only when your game needs it. Recommended BIOS: Saturn USA 1.00 (most compatible) Controls - emulator game list: D-pad Up/Down = move through the list Hold D-pad Up/Down = continuous scroll (fast) D-pad Left/Right = jump by page A = start selected game B = exit to loader L+R = toggle 4M RAM cartridge ON/OFF Z+Y = toggle 240p for supported displays (Gamecube controller) ZL+ZR = toggle 240p for supported displays (Wii Classic Controller / Wii U Pro Controller) Controls - in-game: Start+Z = exit game back to emulator (Gamecube controller) Home = exit game back to emulator (Wii Classic Controller / Wii U Pro Controller) L+R+Start = toggle sound (muting gains some fps) . Shows "SND OFF". QoL suggestions for Z-GX: - 4:3 or stretched 16:9 aspect ratio setting. - Enable/Disable FPS counter. (it is always enabled) - Sub-folders support. - Long name autoscroll on the list could be a bit faster. (IMPLEMENTED in build 20260803A) - Option to pick any Saturn BIOS file. - Turbo toggle to fast-forward. - Selection of RAM/ROM cartridge type to use. Known bugs: - Toggling the sound OFF hangs the emulator. - Saves are not working. (since 20260729 build) (FIXED in build 20260811B) - Title name on the game list disappears when it finishes scrolling. - Have at least 24 games. Position the cursor in slot 000, 001, 002, 003, or 004, press right to go down one page. Now keep pressing Up like you wanted to go back to slot 014 or further, the list won't scroll, but the names will. You will only notice visually if you have your covers assigned. - When you launch the emulator from USB, games/art on the device will be ignored if a SD card is also inserted with the same Z-GX folder structure. SD will be prioritized. - When you launch the emulator from USB, and there is a SD card inserted without the Z-GX folder structure present, it will DSI crash. - 12 seconds pause before the game starts booting, since build 20260811B. - Cover files do not load when you start the emulator from a USB device, yet it will load them if a SD card with the files is inserted before emulator launch. (FIXED in build 20260803B) - 240p.txt file is not detected or generated when you launch the emulator from a USB device. (FIXED in build 20260803A) - 240p mode is not working when you launch the emulator from a USB device. (FIXED in build 20260803B) Compatibility list: Notes for SetaGXHibrido (obsolete): Attachments: - Releases so far. - Wii Channel Forwarder, by cmyksoda, for Z-GX (apps/ZGX) - Wii U Channel Forwarder, by ploggy, for Z-GX (apps/ZGX/) and SetaGX Hibrido (apps/SetaGX/)

Hi.

I've been working on softmodding a Wii for a friend of mine, and I have run into this problem where the Wii will not find/read the USB disk. I've softmodded my own Wii with success, but I just can't get this one to work. Before I get in to the details, I apologize if this issue has been answered in another thread, but I did search quite a lot and did not find any definitive solution.

When I start USB loader GX, it says "Waiting for your slow USB device" and count down for 30 seconds until a new message pops up where I can choose to use either cios 249 or cios 222. The disk is WBFS formated and works great on my Wii. We've also tried with another disk, which also works on my Wii but not on this one. In other words, no copatibility issues with the disk or file system.

So the problem is probably located in the Wii software. System version is 4.2E. I've used the SignCheck utility to get an overview on IOS versions and such, and I've posted all the info below here. I really hope that one of you smart hacker dudes can tell me what is wrong and provide a solution based on the information I've given here. Any help is greately appreciated.
