Several points to note: PSP and nds need to decompress and import iso, cso or NDS files into the corresponding folder. Please make sure that the name of the compressed package cannot be changed after importing the game ROM of MAME and ARCADE, otherwise the emulator will not be able to read the game; Please put MAME's ROM in MAME/roms folder.
ROM of other simulators can just import the zip package into the corresponding folder; If there is a problem such as flashback of the imported game, please try to rename the files and compressed packages to digital numbers. This problem will be corrected in 1.0.8. After the import is completed, please close iTools and restart the chicken simulator.
