Hi!
Here's the answewr
1. yes I move the link file from the game folder to put it in F:\PS3\PS3Games. I rename to Magician and kept the extension as it was.
2. It was named EBOOT.BIN and I renamed it Magician ........ funny thing, I can not see the file extension of the link file, but I can see the .bin extension.
3. it's F:\PS3\dev_hdd0\game\NPEB00242\USRDIR
4. It's NEOGEO Station - Magician Lord
one thing I noticed, if I rename the EBOOT.BIN in his respective folder, for any name..... "Potato.xyz" and point gameex in that folder with the xyz extension filter, it will launch the game with no problem. Since, all the Eboot.bin are in their respective folder, it's not a good solution. But gameex is able to launch the game, just the link file that cause a problem.
Thanks a lot for your help.
I will continue on my side to try to find a solution as well.
