Hi, u guys! I have an urgent question, please answer.

I have not been able to make The CHD's games run on any of the latest MAME emulator. I did download the latest CHD's files. but after trying to run the games, the emulator is still not loading the damn game. I have place the ROM and CHD in the ROM folders but still, I'm having the same old problem.

My question to u guys is, do I need to rename the CHD's to something else, like for example kinst.chd is it supports to read like that or something deferent than that, or what.

I have the ROMs' I have the CHD's and I'm placing them into the correct folder. The ROMs folder. so what's the problem. I did read somewhere in the Internet that the CHD's change. but I just don't know, what is it that change with the CHD's. Is it the name of the CHD's that change, or what? Because as far as i know i did download the latest CHD's via bittorrent

Any help would be greatly accepted. Thank u very much u guys
