DsS Game, in the USA, downloaing copies of copyrighted works is illegal without permission from the copyright holder. However, in the USA, it is legal to make backup copies of copyrighted software and such you own. You however are not to distribute such copies without copyright holder permission etc etc.

In otherwords no matter how you spin it, if you've downloaded a ROM, you've violated someone's copyright. The catch is, unless you are copying something that is still being sold, the copyright holder may not be inclined to take you to court unless you are mass distributing copies of their product or something. However it's still illegal or in copyright violation.

Again, Mottzilla makes a good point and sets things straight. 😊 :thumbsup:

And to add to what he said, one has to be careful when companies rehash a game(or games);
example, the Mega Man collections for GC, PS2, and GBA

Exactly man. Companies also often start attacking prior to rereleases of products. I.E. when Zelda 3 was being rereleased on GBA they started attacking sites that offered the SNES rom.

Anyways, they aren't being mean, they have every right to protect their property.

I'm looking for a PS2 emulator. My reasoning for this is when my roomate's watching tv I'd like to be able to come in my room and play using the computer. The ones I was able to find would only play a select list of games. Are there any good PS2 emulators out there? Do they use the CD/DVD drive to play the disks? I'm not really interested in downloading games, I just want to play what I have.

I'm surprised that Nintendo hasn't made a big deal about the older NES emulators and roms, since they've been doing a lot of re-releasing lately. They've got the classic collection for the GBA, Zelda, Mario, Excitebike, ect. and I hear they may relese more. It's kind of annoying really, I because I didn't pay ~$100 for a handheld NES/SNES player. I want to see more original GBA games.

No, you're screwwed. If you want to play "on the computer" get a video card or device capable of TV in. No emulator at this point could possibly compare to the experience of using the real PS2 hardware. It will remain this way for quite some time as well.

Nintendo probably hasn't made a huge deal over their re-releases vs. roms because they are selling these things so cheap and they cost damn near nothing to produce.

Anyways, I'm with you on the GBA and NES ports, wtf. It was a nice addition to like, Metroid Zero Mission to have the original. However, SNES ports, provided they are good ports, are great. Unfortunately they aren't that great. GBA should focus on quality original games (like Metroid Zero Mission, while a remake its actually an original game, never before see like that before, only based on the metroid concept.

Metroid Zero and Kirby Nightmare in Dreamland (Kirby's Adventure remake) are my favorite GBA games.

Now if I can find a reliable place to download plugins for epsxe...

oh, I tried ZSNES DOS, the speed is almost 100%, but it's buggy as hell :mad2:, especially with sound not playing. Oh well, i'll just try to find a dos version of snes9x, and see if I get a speed improvement...

OK that makes much more sense.

Cyborg whats the speed on ur comp?

Daywalker

P1 MMX at 233 MHZ
2MB built on video
64MB EDO RAM

( it's an old Packard Bell tower that I bought at a garage sale for $10 )

Unless you change the frame rate a bit, I don't think your gonna have a great time with an snes emulator.

I dunno I think at most u need a 500 mhz to comp for it to run smooth. My old comp. was 600 mHz but it didnt run completely smooth but it was tolerable.

Daywalker

meh, I still can run Street Fighter II Turbo, Final Fight Tough, Super Mario RPG, Final Fantasy II, ect somewhat decent, eventhough the framerate is about 7
I don't mind that much, it just runs about 3/4 speed(it's sometimes better to have that when playing certian games)

With a 233mhz, certain games are bound to run slower, like anything using color arithmetic (when they do effects to simulate translucent water or fog) or any special chips like super fx, sa-1, sdd1, etc.

Anyways, you also may want to try an OLDER version of ZSNES. Like around 0.7XX. As it got newer it got slower. Btw sound may not be playing because I believe sound emulation output may be disabled by default.

thanks for the info
btw, I have sound enabled via commandline swiches, because if I mess with the sound menu, the sound stops working after a minute. When that happens, the whole computer requires a restart in order to get the sound working :mad2:
there's also sprite layer problems when playing Super Mario RPG, and other problems when playing BSZELDA...
oh well, just have to keep looking.

ZSNES is not a very accurate emulator, BSZelda is very sensitive, and doesn't work in all versions of ZSNES. Super Mario RPG uses the SA-1 chip by the way, which means it takes even more power to emulate since it must emulate the SA-1. Graphics problems, try hitting the 7, 8 or 9 keys, one of them switches between new and old gfx engines. One may look correct while the other does not. Also one may be faster than the other.

didn't know that about SMRPG :thumbsup:
maybe tomorrow i'll look for other SNES emulators...
though, i still like snes9x better than ZSNES, because, it's runs faster, it has more of a 'windows' configuration, and it has a better handling of save states(and custom save states)

Whatever works best when you are dealing with an older machine. With newer machines though... even then for SNES its whatever works best because none are totally accurate.

*now to contiune on with the discussion*
(but a question first, could this be stickied?)

What Roms have you downloaded, and why?
(the ones that i've mention are because either i can't find them, or they're imports [like Zero Wing] )

I thought it was accurate? Some say its one of the best cause the emulation is perfect.

Daywalker

have you tried to run BSZelda with ZSNES?
it's a big pain in the ass, not to mention that the sound (music and effects) is horrible at best

emulatiors aren't perfect, for example, they can't play every single ROM for that particular system, some of the added processors aren't fully supported or not even supported(like a few for snes9x), but that's usually for one or two special games(like Star Ocean and Street Fighter Alpha 2, for another example, but snes9x supports that), certain import roms has someting different(i don't remember what) that is completely foreign to an emulator, so it won't run; if a rom runs in one emulator, it's not gaurnteed to run in another version or a totally different emulator(like BSZelda not running in snes9x, but it runs under certain versions of ZSNES)
I hope I cleared that up for you 😃

I actually wrote a great reply about this, but mozilla crashed, and I wasn't gonna type the damn thing again. But yes, ZSNES is actually very inaccurate. ZSNES is/was designed to play games, and as fast as possible. Many games that aren't as sensitive, work great, and used to work fast. Newer versions pretty much crippled speed.

ZSNES plays lots of things amazingly well, but other things, it totally falls on. Emulation of the CPU, the SPC700 chip (sound), extra chips like DSP, SFX, SDD1, etc. are not perfect. Never will be.

Also, ZSNES still does not support realtime SDD1 emulation, while SNES9X does. ZSNES and Snes9X still support SDD1 games with GFX packs to avoid SDD1 emulation all together.

and to make things a little speedier, you can use the GFX packs with SDD1 in snes9x

I would say that snes9x would be the best emulator for really old systems, like mine
(and since i got a better updated version of it yesterday, it runs a little bit faster 😃 )

I dunno prolly the reason why it was great for me was cause I had an older version. The sound was great for me because it was actually a great replica.

I already know about emulators not being perfect. I need an emulator that would run the jap version of super mario 2 (US version of the Lost Levels) I always wanted to see how that game was in old school mario graphics.

Daywalker

SDD1 emulation is not "faster" unless your PC is REALLY slow. Realtime SDD1 decompression shouldn't burden you that much, unless ofcourse if you really are running like a pentium 233mhz. ;p

my computer really is a P1 MMX @ 233 MHZ, but i haven't found any roms that need to use those capabilites :shrug:

DsS Game, I'm pretty sure that JNES supports Japan imports, hope that helps!

should of known that zophar had that kind of thing...
thanks Mott!:thumbsup:

now i'm curious about this: would a Neo*Geo emulator run on my system?
(see above or previous pages)

thanks, you're always a big help.

how about we contiune with the general discussion, shall we?

In that case, I'd like to pose a question, and re-pose an old(er) unanswered question.
(By the way, sorry if I sounded rude, DsS Game. I actually was trying to be a jerk, for whatever reason, and in hindsight that was stupid and unneeded. I really had no cause to jump on you like that, and I should have tried being polite before being rude. I apologize.)
(Also, thanks, Vagla, for suggesting the PSX->USB converter- I can now suck at SFA3 without justification!)

1: How would I go about saving copies of my PSX games onto a hard drive in a format that could be read by EPSXE? I'd rather not risk damaging my CD's when I bring my laptop around. Can I just copy the CD's contents to a folder, or would I need to make ISO's or something? If so, are there any programs you'd reccommend?

But they're on Zophar's Domain, and I was under the impression that the point of that site was to have a compilation of all emulation materials that they could get away with providing(legally). So is Zophar's Domain less legit than I thought, or do the sound files not qualify for legal protection, or what?
