Metal Gear Solid 1 PSX disc swap GUIDE

[aar36095]

You all hopefully know you can easily boot backups on V9+ machines, and MGS1 is an a$$ to get through. So, heres the guide on playing ALL of it totally from backup discs. When you are playing thru MGS1 and you beat Sniper Wolf, and go down the steps to the Blast Furnace, it asks for Disc 2. I really hated asking my friend for the original disc, as I had the backup. No matter how many different times I tried swapping to continue the game, it wouldn't accept the disc. So I decided to bypass it and read up on the Net. Most people using their PSP's to play Ps1 games are actually playing MGS1, and they couldn't get past the Disc 2 swap, since the psp's emulator did not allow for ejection of ISO's. A very smart person thought of using cheats to bypass the Disc 2 check, and I easily did the same on the Ps2.
The forum's guide displayed the cheat, and to me, it looked awfully damn close to what Action Replay and GameShark PSX codes look like.

Steps:
Get a GameShark lite or use the bonus disc that comes with the ps2 edition.
You can also use a Action Replay ps1 disc.
When selecting MGS1 cheats, select Add New Code. Name it MGS1 Disc Swap Fix. The code is:
800B7518 0002

Start the game using DISC 2, yep 2, and load up the save that is still on Disc 1. The game should actually load the save as normal, as if you were on Disc 1 still. Collect any items you want/need from the warehouses around you, and (VERY IMPORTANT) run into the Comm Tower. The screen will go black for about 5 seconds, as the cheat kicks in. Now, leave the Comm Tower to go back to the Snowfield. Again, it will black out for a few secs. Be patient. Now, go into the building with the stairs. If you did everything right, throw a chaff, and run thru there. Head down the stairs, and again, if you did everything right, you will be in the Blast Furnace. YAY! You now can load the game with Disc 2, and play normally. Make sure to turn off the MGS1 Disc Swap Fix cheat, if you use AR/GS normally with MGS1. If not, don't bother. Do not worry about the end of the game, it saves as Disc 1, and then you restart the ps2 and load up with disc 1, and play all over again.

I once had a skip disc check code for the European version "I think it's still on my cdx" of special missions that requires a disc from the original MGS1 game unlike the US version where it plays straight from the disc I never tried it on the ps2 though to see if it restored compatibility due to the disc check being bypassed.
Multiple disc based psx games seemed to have compatibly issues with the earlier ps2's.

I wonder if it can be condensed I don't feel like type all them codes into AR.

[aar36095]

There sure is alot of repeats of the code D00EAE5C FFB8. Wonder what would happen if you just input the non repeating codes...

(lol, that code for AR would probly take up your whole memory card. ((oh wait, that whole code is only ~1kb)) )

There sure is alot of repeats of the code D00EAE5C FFB8. Wonder what would happen if you just input the non repeating codes...

I think that would be a very bad idea, as codes of the type: 'D0aaaaaa vvvv' are useds as 'if' statements, executing the next code line only if the value vvvv equals the 16 bit value stored at address aaaaaa.

So those 'repeating' codes are in fact intended to prevent the patching from happening when not needed, because then it might affect something else. So removing those codes would make the patching codes active all of the time, which could prevent the game program from working right. I'm not sure, since I don't know what that program uses the affected RAM area for.

Hmmm, that does sound like a very piece of vital information to the PS in general, but what blows my mind is why the code is 900+ characters long. Is there that much of a difference between this Game Buster and a PAL Action Replay?

[kevstah2004]

I tried the long code and it didn't work on my AR CDX
I'm unable to test the Xploder code.

[fortune2k]

is there any other way without getting a cheat system thing my brother has action replay max the ps2 1 i think can that be used to do this coz i can steal it off him and continue my game
