Disc swap not recognised in most games

[GoogleCodeExporter]

The only multi-disc game that recognises a requested disc swap is Resident Evil 
Code Veronica.

D2, Deep Fighter and Shenmue 2 don't recognise the new disc once swapped, and 
sit at the 'please swap disc' screen. Skies Of Arcadia resets to the DC menu 
screen once the new disc image is selected.

Note - If I haven't mentioned a multi-disc game, it's because they don't have 
the new game option when using a disc other than the first (eg. Alone In The 
Dark, Shenmue 1). Maybe they don't work either.

Tested on r78.

Just try older revisions and see if swapping worked at some point. If you get a 
crash on older revisions try disabling the dynarec.
At least D2 is known to work before some hacks were taken out. Dunno if the 
rest also fail cause of that or something else broke.

I've just tried the same games on 1.0.3, same results - only Code Veronica 
works. No crashes, the emulator just sits at the 'please insert other disc' 
screen.

I'm using GDI images if that makes any difference. Don't have CDI versions to 
test.

That's why I said "older revisions" and not "older versions".

Ha, so you did say "older revisions". It's late here...

Did you fix disc swapping yet? :P

As I said, swapping used to work at least for D2 up until some point. Of course 
the hack was so bad that it would make the emulator crash about 90% of the time 
if the Dynarec was enabled. It would crash on interpreter too I think, just not 
so often.

What I want to know is if the rest stuff worked when D2 worked (and if the 
change that "broke" D2 broke the rest too).

Any advance on 'up until some point'? :)

I'll try a few different revisions tomorrow.

I was under the impression that disc swap worked *in most* games. Can you get 
me a list of multidisc games so i can check ? :p

The games I listed in the first post are all the multi-disc games where disc 
swap can be tested quickly (ie. by inserting disc 2, then trying to start a new 
game and being asked for disc 1).

So that's:
Resident Evil Code Veronica (swap works)
D2
Deep Fighter
Skies of Arcadia
Shenmue 2

Other multi-disc games (Shenmue 1, Alone in the Dark) have the 'new game' 
option greyed out when using a disc other than the first), so they'd need a 
save near the end of a disc to test.

Alright, try with this revision:

http://www.megaupload.com/?d=9ULSOEP8

If the stuff you try crash, try on interpreter. It might take a few tries.

Just want to know if any of those "work".

Disc swap works fine with that revision (r48) on all 5 games listed above.
I had to use Interpreter mode as Dynarec crashes, but each disc swap worked 
first time.

Well I'll be damned... it looks like we hit the jackpot. Care to try with r50 
too? That was the last revision uploaded on the downloads list here, so getting 
it won't be a problem.

We might be getting somewhere - disc swap in r50 does NOT work - same results 
as in r78 (Resi CV disc swap works, the other five games don't work).

Four games, even.

I see. It's all good then. The cause is known and so is the solution...

Just don't expect those to be fixed any time soon. Not by myself that is, dunno 
about drk.

Is anyone willing to spell out this 'cause' and 'solution' for me?  I can't get 
r48 to run on my pc (win7x64 seems to refuse to install msvcp100.dll) and I'd 
really love to play past disk 1 of D2.

Much appreciated!

For the (off topic) record, I had the C++ runtimes, but they were corrupt or 
something and had to delete/reinstall msv##100.dlls

But super thanks regardless!

Personally, I investigated by disasm game code.
I seem that it needs busy state after tray close, like below.
(But, I only checked in one game "Kaen seibo".)

curr impl.
 GD_STANDBY
 (swap dialog open)
 GD_BUSY
 GD_OPEN
 (swap decide)
 GD_STANDBY

fixed.
 GD_STANDBY
 (swap dialog open)
 GD_BUSY
 GD_OPEN
 (swap decide)
 GD_BUSY[BSY:1,DRDY:0]
 GD_BUSY[BSY:0,DRDY:1] (this state is important in my case.)
 GD_STANDBY

Hmm, okay, will look at implementing it this way then

Just tried swapping discs on D2 with r136. Just hangs at the swap screen. Is 
this still being worked on?
