it's called desync(hronization). say, the input recording (the movie) is stored in a separated place from the savestates. you use frame advance (frame by frame playing/recording). you record up to frame X, savestate there (slot 1), creating segment A. now you keep recording up to frame Y, savestate into slot 2, that makes segment B. now you load slot 1, and start doing the segment B differently, let's call it B'. if you accidentally load slot 2, your movie is screwed : the input recorded so far, and the state the machine is now at, represent 2 different branches (B and B') and the sync is lost. if you start recording again, you will append incoherent data to the movie, since the new moves you're recording only have a meaning into a context where the previous input cannot lead to. playback of the movie will show the intended movie up to frame X, then the character will do crap. if you have bulletproof recording, the movie that brought to the state in slot 2 was saved within the state, and has been loaded with the state, keeping both in synch. hope that was clear enough (I neved tas'ed <_<). I highly recommand that you get in touch with upthorn. he already coded rerecording features into others emulators, he will be able to answer programming questions, as he said he wants to help the community to get a sms rerecording emulator.

OK, I understand the first part of your message and how it'll do crap. However:

Are you suggesting to switch a savestate during the final playback? This sounds like cheating based on usual TAS rules. If I understand the (usual/current) rules, the movie is supposed to reflect a run that is doable on a real system/cartridge with an input feeder. It shall run from reset state or possibly from a single start state. Correct me if I'm wrong. If you load a savestate for the purpose of playing back inputs to complete level X then another savestate to do level Y, the game engine data is "hacked". When you guys make a perfect-play video, don't you always record levels in *order* ? What if you have a full game recorded, and then later you find a way to optimize the run on some level, what do you do?

the movie is saved within the savestates to help the player always having a synchronized movie when he switched between slots (bullet proof), but the opposite is false. savestates are only a way to redo, and rerecord some parts of the game into the movie, which is saved separatedly. they are only employed during the making of the movie to assist the player. the movie is a mere recording of the input (it also saves the number of times the movie was rewind ie some parts were redone, rerecorded thanks to savestates). players only submit this movie, the rules forbid to submit savestates and the first command in the movie MUST be a hard reset (optionnaly SRAM files are accepted). then, you playback the whole movie which is now continuous ; that's how the divx here are done. hope that clear things, and I did not say anything wrong u_u.

I want a rerecording Master System emulator. But I don't know how to make one :( i'm doing a phantasy star run with the gba version, but it's not fun cuz there's graphical errors and it's slow. i wanna use the real version.

Didn't phantasy star also release on the Genesis? I have slight memories of seeing that. Edit: Yeah, it's available to genesis.

Then I'd say its the hardest genesis rom to obtain, as despite the searching I've done for it over the years, I've never actually found it, only heard of it existing. Does it even have any real "uprgrade" on the genesis version though? eg. enhanced music, graphics etc.

Woha! I thought it was included in the GoodGen library? Does the game have another title in Japan? Like an original title. Might be easier to search for that right? Edit: BTW. I reckon that someone on these forums has the original cartridge. I know I've seen it in a collection list of some sort. Perhaps we should dump that cartridge eh? =)

This topic's kind of old, but the Genesis Phantasy Star was something I also wondered about now and then. And I just came across this:

The Megadrive version of Phantasy Star is in fact nothing more than the Master System ROM in a Megadrive cartridge, with enough start-up code to put the system into its Master System backwards compatibility mode; it can be regarded as a Master System converter integrated into the game.[/quote] I suspected this was the case, but never heard anything about it. So we can all stop looking. ;)
