Hello @Xale007 . Unbelievable work. Dreamcast emulation on Wii sounded like a dumb idea, but with the constant releases and improvements you have done it seems plausable to have lots of playable games from the last SEGA console.
I was testing some of your buids, but it's hard to keep track of everything new for the Wii. I can't help with the compatibility for now, sorry . But I want you yo know one issue I'm having with the latest releases.
I'm using a PAL Wii from launch day (seems that is a little special with memory). I load the app from the HomeBrew Channel from the SD card. I would like to have the games in the USB drive since I'm running out of space in the SD card. The USB drive is an external 2.5" Western Digital 4 TB hard drive formated as MBR partition, FAT32 with 32k clusters (Allocation Unit Size: 32768), and set as ACTIVE & PRIMARY.
In release 0.64 I was able to load the app and run games from the USB. GDI images with the .bin and .raw are stored in root://dreamcast
From release 0.65 and upwards I can select games from the USB but they don't load at all. I can't even run the bios. After a few seconds of black screen I'm sent to the Wii's health advice screen.
Also from release 0.65 and upwards, if I try to run a game from the SD card I'm sent back to the homebrew channel before even running the bios. I have to unplug the USB and then I can run games from the SD card.
I get no code dump screen or errors. The emulator just redirects me in those cases. As I said, build 0.64 was working perfectly. I tried up until 0.695 which I saw in Github.
I had a similar issue with ioQuake. I was getting a "not enough memory" message when trying to start a match when the USB was plugged (even if everything was stored in the SD card). @Mayo1990 was able to fix it. He said to me that: "The issue was because the mounted (although unused) device would take memory off the console."
