Sounds very logical to me 4x interface might be slower adding a delay would fix it.. I have also done this before for madcatz vmu and rumble pack to get them to work.. only slight delay seems it would fix it..Roel wrote:To add my 2 cents, the original Rush Rush Rally Racing didn't support 4x VMUs either, but I fixed that issue and my newer games do support them. I found that a standard VMU writes blocks almost instantly, but the 4x VMU that I used for testing took much longer to write each block and it incorrectly reported that it was ready to receive more data before it actually was. Adding a slight delay between each write command solved the problem.megavolt85 wrote:need ask guys from Junkyard to check their memory card in other homebrews, it is possible that the problem is in the VMU itselfhombreimaginario wrote: THen we realized is a very, very rare item and that part of the review was basically (I think) a joke
I had a Chinese VMU 4x that worked everywhere except homebrew, but the exact same VMUs worked fine for others

Re: Xenocider/Project Q
if the problem was in the write speed, then WINCE games would not be saved
the problem is in the crooked KOS driver, which simply bombards the controller with a bunch of unnecessary requests, checking if the VMU is disabled
adding a delay is not a solution to the problem, but only a crutch

Re: Xenocider/Project Q
I didn't realise that throwaway joke would cause a discussion in itself haha! The 4x memory card (the official sega one) is known to not support various retail releases, while the third party ones do. Not really sure anyone knows why without looking into the firmware of the card but that's way above my level of expertise! It was just a bit of an 'in joke' nothing more
Here's the known games it doesn't work with:
White Illumination
Dynamite Cop 2
Air Force Delta
Maboroshi Oboro
Kitaihei Gold
F1 World Grand Prix
Carrier
Nanatsu No Hikan
