Question about S.states and game compatibility!

don't use save states, stick to memory cards. only a few games with bugs or crashes need save states. personally I wouldn't use saves states, it will mess up on you.

I have those 2 games and they work fine in psxeven

Meh.. I thought I heard psxeven has good savestate support unlike epsxe.. There's really no reason for me to use psxeven otherwise (All the games I have work fine on epsxe)...

Well, you can test MGS on PSXeven and creating a save-state for it...

1. what in the crap do you mean "good save state support unlike ePSXe". it's NOT the emulator's fault. its the nature of emulation and save states themselves!
2. save states dont work for MGS at all
3. i use save states in almost every game i play. they are excellent, and i rarely have problems. HOWEVER always make memory card saves as a backup. and when you have a problem, the FIRST troubleshooting step you should make is to not use save states.

It is the emulator's fault. It simply does not save enough things. It might be the plugins' fault as well, as they might not send correct/enough data back to the emulator.
SNES, GBA, NES, maybe N64 : all of those have emulators that support save states per-fec-tly.
Yes, it's more complicated in PSX, but it's not impossible...

1. This is true.
2. I just merely kidding
3. Unlike other emulations, Playstation relies on CD checking, an example would include constant read and writes to the disk.

Try using them if you are sure that the CD or image isn't in use before saving.

I use savestates on MDECs in FF9. They proved to be effective even on CD reads and writes.

So what you are asking for is 100+ MB savestates to hold all the data that is being accessed in a given moment on a PSX game, plus the registers, instruction pointers, ram state, etc etc etc. Then you have the save/load time for a savestate that size... I think that's unreasonable.

Just pay attention when you are saving, it's not that hard. Or, as it's been said, play the way the game creators made it to be played, and use memcards.

It certainly won't be 100mb (or did someone from a dev. team of a PSX emu said it'll be 100mb?). Maybe giving the option to use either 'compact' s.states or 'full' s.states would be nice. Hard to do? Yes. Possible? Also yes. Useful? Very.
I'm sure I'm not the only one who is willing to sacrifice up to 10MB of space for a fully working savestate.

hi everybody!!! i'm new and with a big problem.
my pc:amd barton 2500+, nvidia fx 5200 128 mb,motherboard gigabyte ga-7vt600-l
i have PSXeven 0.19 with peops soft driver 1.17 and 1.14 in GPU; eternal spu plugin 1.41, eternal spu plugin lite 1.41, peops sound audio driver 1.9;xeven's cdr driver;segu direct imput keyboard.
i'm trying to play final fantasy IX ntsc usa and after a short period of time comes the error:
error: Reserved opcode being called: 0x [email protected]
-- emu released due to error --
*ended
and this is the end
PLEEEAAAASSEEEEEE HEEEEEEEEEEEELLLLLLLPP MEEEEEEE

are you using save states...? if so, dont.

have you used ePSXe 1.5.2 or PCSX? or try a different CD plugin, or make an ISO.

yes but with epsxe the game is moving too fast and i can't see the menu where u choose the action . this was the only emulator that made the game work fine............ :???:

if it's too fast, you need to enable frame limiting and set it to the proper amount (you can use Auto..or 50 for PAL and 60 for NTSC).

No, in order to be able to give proper access to any given data that is supposed to be loaded in the game, you'd need to back up most if not all of the memory the emulator is currently using. A quick game on FFIX showed a memory usage of about 60 (game intro) to 80mb(fighting). Ok, i went a bit too far away...

It shows me only 50MB in battles.... Maybe I'm not using proper tools, or maybe it depends on the settings.
And what does that have to do with anything? Snes9x and zsnes both use around 16 mb of memory usage and VBA uses 40 (Independant on rom size, I think, because both roms I tried were different in size, and quite small anyway (public domain)).
The savestates they produce are around 100 kb.
Sure it might even be 10MB (zipped) for playstation (which I highly doubt), it still won't equal the amount of used memory.

So wich of those emulators you mention stream data from a cd? Wich of those emulators have 700MB games, with videos and music that are directly and continuosly streamed from the CD? But anyway, guess what, you are right. As it is that easy, go on and code it. I'll be waiting for it patiently. PCSX IIRC is open source, you can start your work there.

Sigh.. You aren't a coder either (at least not in the level of an emulator coder, right?) so why do you say it's impossible when you don't know that for sure. I'd give you examples of many things people sayed was impossible but was easily or not-so-easily done later on, but I'm sure you know such examples yourself.
And why do you get offended for no reason? I never said it was easy, in fact I said it might very well be hard to implement. I didn't demand anything, nor did I 'whine' about anything, all I did was suggest a feature which would, in my opinion, double the quality of the emulator. There's really no reason to get offended by that.

ok a frame limit might help on the speed......but what about the error???? the emulator is bad or the rom???????

and for ps2???? anybody knows a good emulator. i have tekken 4 and it doesn't work

rom eh? where did you get this rom....?

btw, dont double post, you can just edit, and on the PS2 thing, wait a couple years
