Ok Ok I admit, dont complain if you guys already know this but right now I am very excited about this.I dont really know how it happens and I dont really think its possible but the fact is this is absolutely true.This will not be useful in all the games but it would be nice if you people can figure out and tell me if it applies to some of ur games too.

So what I did was one simple thing.I was playing my Brian lara cricket on epsxe.I did a save state at one point and then existed the game as well as epsxe.

Next step was to mount another(Re-2) cd image in my virtual cd rom drive.Next I went to save state directory of epsxe and renamed my save state from brian lara cricket(to the corresponding number of second psx cd I mounted).

In the next step I run the second cd (RE-2).I played it for a while.Pressed escape and then loaded the save state that I just renamed and surprise surprise ,What I find is Cricket again.

Now how in the hell is it possible?I mean the cd mounted is not cricket and I am playing the game(one full innings, then it hangs).Now this is absolutely ridiculous.How could someone play this much of a game from just 1.5 MB save state?

I tried the same thing with Carmageddon and I can play one full stage .It does load up in dino crisis-2 too but cant afford screen changes.

Now will someone tell me whether I am missing the point somewhere or this thing happens in your games too?

I think it wont be of much use to you people but for someone like me who loves batting in cricket its really nice.

If you guys try it(I am not sure you will) you can write down in this thread for how long your particular games play(if they do play) and whether this thing was worth mentioning on this post.

those savestates aren't really 1.5MB but are compressed to 1.5MB (they can be opened with i.e winzip, try it). Anyway, i think they're actual size is around 5MB (you can crucify me later.. ). And since the savestate pretty much dumps the whole emu status (i.e. memory, plugin stats,register stats etc... , i think), and because some games have the current stage preloaded, its possible to play through the current stage or at least through the current scene without having to read from the cd, i think that's happening with those games....

yes, but be careful

that is right, you can do that. but many times it shows a "blue screen of death", mess up you CD Rom drive, or both. I lost my 52X drive by doing this, so watch out!:dead:

At present I am trying only with isos and after your warning I will think twice before trying it from my good old 12X cd drive.

Btw I just used this technique to play WINNING ELEVEN 4 and it works perfectly.You can complete the match make selections change camera angles(I mean you can do every usual stuff except from loading formations).It does not hang anywhere(not even after half time).

 

[Prafull]

Just curious to know,If I try to make that save state run on another computer.Will that run?Now If that happens it will be the most dramatic thing I have noticed since coming into emulation scenario.
I mean 1.5 Mb file and you playing whole lot of game(with sound and graphics).I just cant believe it.Something somewhere is being missed by me.

i beleive its the same thing as when you take the cd out of a psx. you can still play for a while, but when it needs to get more data from the cd the psx will freeze

 

[Zster]

They're gzipipped and is actually a dump of the the full psx memory size ie 2mb video 512k sound and 4mb(I think) main ram and the registers. In AdriPsx you can load a save without even having to boot the CD. Just open up AdriPsx go to load state and play. Do note this isn't going to work too well in games that require xa sound.

This opens up an interesting possibility..... an 'ePSXE savestate archive' website will now serve two purposes:
- a savestate archive website (duh! )
- a 'PSX game demo archive' website (!)

Hmm I checked that and it seems to work but I think save state is not zipped in adripsx(its over 4 MB).With newer(upcoming) version of adripsx which has supposedly much better compatibility and sound (at present I just cant get sound in most of my games) I think it will work much better.(I think it should work with any emulator that supports save state though).

I was thinking on similar lines.It would be really great feature and it will surely work as a demo for the real game.But I am not very sure whether such thing will be allowed(with sony already trying to get a chance to shut down all emulation related work).

I think I said that before but I am repeating it again ,can anyone else try it and post here which games it works well and which games it didnt?Now thats asking for too much I guess.

 

[Schädelkeks]

hey time killer...

i don't think epsxe has killed your cd-rom drive because the cd plugins can't control the internal mechanic of the cd-rom drive.

I don't wanna explain that in detail so i stop that now

 

[Fou-lu]

Yup, a program can't destroy hardware (except a virus attack on the bios or a out-of-control-maniac-robot-killer). I think you lost your cdrom in the same maner I'm losing mine, wear damage. It has about a year, so I think that's time to say goodbye for it (it's a 52x creative drive). About the "demo feature" that this savestate archive may represent, it would be very nice. As you wouldn't need the game to see a particular spot of it (or various), so you can analyse the game and see if it's worth buying or not.

 

[gerbilcannon]

Unless the program forces your monitor into a refresh rate that it doesn't like and it goes pffffftzscsh or a program overclocks your video card too highly and it goes pffffftzscsh or a program overclocks your cpu too highly and it goes pffffftzscsh well you get the idea. ^,^

Yeah I was wondering about the legal issues as well.... this is a very hazy area however.

Now, to a more interesting observation.... I used to be able to play Ridge Racer one using a regular Audio CD... so what I did was put in the Ridge Racer CD, wait till the title screen shows up, and then put an Audio CD I want in there. Would this mean that the *entire* program for Ridge Racer 1 get loaded in memory? And thus, the savestate would contain (gasp) the whole game?

 

[Fou-lu]

yeah, i remember that trick(I used to play Metallica on it), Ridge Racer is among the first releases for PSX, so i wouldn't be surprised if the whole game was loaded in memory. I think Batlle Arena Toshinden 1 has the same ability(after you chose the caracters)

 

[Prafull]

I dont have ridge racer or battle arena toshiden.I think you are talking about an actual psx here(when you talk of whole game loading).
As far as a save state containing whole game goes why dont you try it and tell me(if you still have that ridge racer cd ofcourse).?

 

[kairi00]

I ain't got Ridge Racer anymore.... left it back home for my cousins when I moved here.... anyone else has it and willing to try?

 

[Prafull]

Administrators comments please!

I should have done this before but now I want to know from an expert(who better than administrators of this site?)

Ok I hope you read the issue above ,so what about the legality of this issue?Is it legal? I think downloading memory cards is supposedly legal (or is it?).So I think it should be no different with save states(but then save states dont work in an actual psx).

Ok I am not sure ,so you guys tell me.(One thing I am sure about is that one of our two most active administrators Bgnome and Sxamiga will reply to this).

 

[Prafull]

Hi everyone again,not really want to make a useless post but it looks all experts are busy in great new site(NGEMU).No one is replying to this.

Where is everyone?

 

[kairi00]

We're still here... and I'm not an expert in law, so I can't give you a qualified opinion on this matter.

However, it does seem like a grey area. Downloading memcards are perfectly fine, since you are not able to digitally reproduce a game that way. However, with ePSXe savestates, there is a possibility to replicate part of the game, so there might be some legal issues there... but again, it's a grey area.
