SOLVED - MGS Disc Swapping

goobatroopa

So I've got to the part where you swap discs. Using the retroarch menu, if I choose disc 2, all it does is resets the emulator and loads disc 2 as if it's a new game.

I cannot also change the disk index in the Disk Control options.

I've tried adding a m3u file but it still resets. It doesn't matter if I choose the .bin file or the .cue file, it still loads the game as if I booted it fresh from ES.

I've had a look around and I cannot find the solution. Apologies of there is one on here.

Used this method which Mitu helpfully explained.
Disc1 to disc2

Thankyou

It is easy to make an additional .m3u for starting the game on disc 2 by copying and then changing the order of the index .m3u

MGS (Disc2).cd2
MGS (Disc1).cd1

Then the memory card needs to be symlinked to the first one

cd ~/RetroPie/roms/psx/MGS/ #go to the directory with the disc
ln -s "Metal Gear Solid.srm" "Metal Gear Solid (Disc 2).srm" #symlink the first .m3u/.srm to the second .m3u/.srm

Will have an additional entry in emulation station, I use folders for multidisc games, completely optional, though I find it convenient to be able to start from disc2 when I am on disc2.

If you didn't know; the updated lr-pcsx-rearmed and pcsxr added the option to change the psx cpu speed again.
Changing it to ~77-83 for MGS will fix the slowdown that was in first-person and boss-fights.

I didn't know this. Thanks man.

@goobatroopa
Yeah I remember this setting a long long time ago for x86 I think. So it may never have been implemented to lr.

I think this will work for a few other games but I still haven't tested. Chrono Cross battle sequences maybe, there's not terrible lag maybe I imagine it. Brave Fencer Musashi will likely fix when there is 6+ enemies on the screen.

@Efriim Great. I haven't yet implemented it but I will do so and let you know how I get on. I got used to the slowdown to be honest, but I like things perfect so I will get to it.

goobatroopa

Ok any idea how I change the cpu speed? Can't seem to find it in the RGUI.

Efriim

@goobatroopa It is in the updated core.
"Quick Menu" - "Options"(/"Core Options"; if they were frugal about labeling settings). "PSX cpu clock (default 57)"
