Slamo, me and a friend are testing setting up to try out PCem, and I wanted to know if you had by any chance looked into 98lite? I'm wondering about the validity of using resource reduced versions of a 98SE installation for making TAS runs, though obviously we're in the early days of discussion on this.
Here's a video demonstrating 98lite's features: https://youtu.be/rCwtA9e3YRI
And I won't say where, but it's not hard finding a copy of the professional version, which actually lets you do a fresh installation of 98.
EDIT: Want to note that based on the stats from the video (though testing would be in order on our end regardless), performance impact on games was negligible, less than 1%, if unfair results is a concern. Again though, merely interested in the streamlining of this process for any potential future in Windows 9x runs.
