i think there's a difference between "genuine" emulation and just "accurate" emulation. now I THINK what's going on with psx emu is that it's running the game just as original psx hardware would, except it's passing interpretted instructions to our PC's hardware. since it's NOT running on psx hardware, it doesn't have the same LIMITS as the original psx. your PC isn't actually speeding up the emulation in any way at all, but where there is extra power needed, the emulator can draw on the extra firepower of your PC's beefier CPU/GPU/RAM etc. the emulation is still ACCURATE, so to speak, but you are missing out on the "GENUINE" experience. anyways, i'd rather have the current state of the emu over the "genuine" one. i know this is basically what a couple of you already said, but i just felt i had to state it in a different way. hope it's clear enough for everyone to understand. I agree with this viewpoint, too. While pSX's more accurate emulation of a Playstation is what I like about it, I've no doubt that the slowdowns and any other bugs experienced on an actual Playstation were _not_ intended by Sony's designers, and even less by game designers. ePSXe, for instance, gives you the option of running games with enhanced features, and of tweaking the emu for optimum results. I enjoy this. However, I also enjoy pSX's more accurate, less tweakable approach to emulating _what the Playstation's designers intended_. If I really wanted the actual Playstation's flawed performance, I'd dig my old Playstation out and use that - but I haven't done that for years. A few years back, I bought a copy of Bleem! before it went bust, was rather disappointed, then discovered ePSXe and put the Playstation away. I've tried many of the other PSX emus that have appeared on the scene, but ePSXe and pSX are the only ones that I see myself continuing to use - each for their own particular approach. May I say, pSX Author, many thanks and congratulations on your emulator _and_ your approach!

I forget where i got this info from. but i rember reading somewhere that playing the game from an iso is the reason the slowdowns are gone, when playing from a cd-r or original they are still there, it probably has to do with the great cd reading code pSX author has written.
the parts where the game slows down is where it has to get a lot of information from the disc, and this info happens to be on opposite sides of the media
disclaimer: this info could be not 100% accurate

although the emulation is very good (better than the original ), unfortunately i still get those ocasional lock ups when passing from one area to another or when passing from the regular castle to the inverted one

hey. sometimes castlevania hangs for me when entering new rooms, and i also encountered that dialog-delay that was mentioned somewhere else on this board. so my question is... what do i do to fix this, it kinda ruins the experience of plaing this game to have to walk long distances and whatnot all over again just cuz it hangs.

Try with the -r command line option.

I noticed this slowdowns in epsxe so I decided to give pSX emulator a try and it worked like a charm, no more slowdowns in castlevania SOTN although there are some dialog-delay

While the lack of slowdowns is nice in most situations, there may be a few games in which the developers deliberately gave the playstation more than it could handle. I mean, it's possible that a few games slow down on purpose. Because of this, I agree that there should be an option to turn this on or off.

I would have thought there'd be more effective ways for game developers to slow a game down than to overload the Playstation, covarr. Apart from anything else, this way of doing it might well have different results on different Playstation versions.
Although bad coding might be one reason why Playstation games slow down, I would doubt that any Playstation game developer's coding would be so bad that they wouldn't know how to control game speed... ;-)

i also have the short pauses before dialogs (and sometimes while accessing the start menu in the game), but the worst thing is, for me anyway, it will lock up sometimes when changing scenes (like thru the CD hallways), Totally random when it does it, if i reload and go thru the hall that froze, it'll be fine. I'm just saving ALOT to get around it. Also, the music in the first area fails to loop correctly. The only other thing keeping it from being perfect for me is the black borders during gameplay. If only pSX had a real screen stretching option like in most other emus. When i play sotn thru my tv out, it looks like a letterboxed movie. It was the same on epsxe tho. overall, no complaints as my real psx died a long time ago and i can finally play my sotn cd again.

Playing the game has given me virtually no slowdowns. I love that very much.
As for the hardware slowdown topic here... I agree that if the programmers of a game *wanted* a slowdown, they would know how to properly program it. The fact that this game (and others) don't slow down like they did on hardware simply means (in my opinion) that nothing was implemented to intentionally slow down the game, and therefore they weren't intended to slow down. At best, the programmers probably didn't want to take out things or reduce quality to make these points run at normal speed, and so they just left it, figuring it was no big deal if a few points slowed down or lagged a bit. The fact that many of these slowdowns are or can be (by changing the disc-reading options) easily eliminated on the PS2 just further proves the point. Don't look a gift horse in the mouth, just enjoy the emulator.

The slowdown made it to the PSP?! That's awesome! I know if I had played it on the PSP and seen that same slowdown, it would've put a smile on my face. As it is, I don't like playing anything on the PSP. It has the most horrible diagnal-sensing I've ever seen for a d-pad. I played Mortal Kombat 2 on it and had the hardest time ever getting my character to jump forward and back. After having the same problem with a couple other games, I put the PSP down and never touched it again (it wasn't mine... I wouldn't just blow money on a handheld I haven't tried yet). And I never liked using analog sticks for games that have no right using it. So I refuse to buy or further play the PSP. But maybe I'll play it just for that game, just for the slowdown.
