I tried out the recording function in Mame++ 0.117. I replayed my input to avi record, and when I start avi record it goes like 100 times slower. Is there are any alternative other than this and a screen capturing programme?
If it goes extremely slow as Mame++ records to AVI then probably not. AVI Record through ++ is still your best bet because even if it runs slow as it’s recording, it’s recording every frame and the resulting movie will play back at the correct speed so you end up with the final product you wanted anyway.
Camstudio might be better. It’s free.
