Playback problems w/ Sega games

Post by BBH » Wed Sep 09, 1998 12:30 pm

First of all, it's great to see the site back. I missed checking up on the latest uploads every day. All of the recordings that were uploaded while Zwaxy was gone all seem to be there, which is surprising.
<p>

Anyway. During the downtime of the site, I tried doing some recordings of Sega Ninja/Ninja Princess on MAME 0.34 Beta 1. I had some pretty good scores, but I forgot one of them and had to play it back to see what it was. Except, it wouldn't play back correctly... the recording ended up dying all three times on the first level. I tried playing back the other versions, but same thing. :( So I decided to try making a recording without sound to see if that would work... no dice. I couldn't figure out why they were affected... later I tried making a recording for My Hero, but same thing happened. Both with and without sound. So, when Beta 2 came out I tried recording and playing back the games again, and they STILL won't playback correctly. I downloaded Angry's Flicky (Set 1) recording to see if that would at least playback right, but that doesn't work either. And, as usual, I tried it both with and without sound.

<p>

All of this leads me to believe that all the Sega games that have been added since 0.34 Beta 1 won't play back properly, maybe even some Sega games before then too. Why is this? I wish I knew... here's hoping Beta 3 will let us record properly, but I doubt it. :P

Playback prob's - possible solution

I ran into some problems getting my Flicky recordings to play back, but was able to replay them.
<p>

Normally, when I playback a recording, I immediately press F10 and enable frameskipping to 1/4 just to speed things up. With the Flicky recordings, I saw all sorts of weird things happening when I did this (Flicky actually passed through walls/floors). I then tried playing back only pressing F10 to unthrottle the game, and it played back fine.

<p>

The Sega games may rely on every displayed frame to enable collision detection and/or other important game control features, which may cause problems playing back the files with frameskip enabled (or even disabled, if it was enabled for the recording).

<p>

I hope this solves the problem.
