Missing In Action - NOW *sort of* PLAYABLE IN PROSYSTEM EMU!

[Underball]

So as I was poking around the prosystem.dat file, seeing if I noticed anything peculiar - I realized I didn't have an entry for Missing In Action, even though I knew it didn't work right in Prosystem.

 

After a bit of testing - I figured it out.

 

Here's the proper entry:

 

[017066f522908081ec3ee624f5e4a8aa]

title=Missing in Action

type=2

Pokey-false

controller1=1

controller2=1

region=0

flags=2

 

 

Turns out it needs "type=2" because is a 145kb rom, and it need "flags=2" because it uses the same weird ass banking scheme as Kung Fu Master.

 

I've attached the file for those not wanting to edit it manually.

 

Plays perfect now. Without this entry in the prosystem.dat, the game is correctly identified as type=2, but it doesn't automatically identify the proper flags=2 banking scheme.

 

UNFORTUNATELY - I just discovered taht once you pass the first stage and go to "bridge of fire" you get nothing but garbage.

 

bummer.

I'll have to try that out. Though I don't thing the flags entry relates to banking, since Kung Fu Master doesn't use any banking. I'm guessing it's something related to timing.

I was just going to mention that it gets screwed up on the second level but you beat me to it. I wonder how many of the levels are playable?

OK, it looks like whatever level you select will work until you die or pass the level. So you can play all of the levels one at a time but not all together. Better than nothing I guess.

how do you do a level select, other than starting on the first one?

It's the difficulty switch. In ProSystem hold down F6 when you start the game, it will start cycling through the different levels, let go of F6 when you see the level that you want.

Not sure if this will help but here is a little chart I made while translating from Prosystem Cart type to cart "header" cart types.

 

Prosystem uses the following cart types...

 

prosystem type 0 -> 0	Normal Cart
prosystem type 1 -> 2	Supercart
prosystem type 2 -> 10	Supercart with additional ROM at $4000 (Large)
prosystem type 3 -> 6	Supercart with additional RAM at $4000
prosystem type 4 -> 02	Supercart no additional RAM/ROM
prosystem type 5 -> 256	 F18 Hornet
prosystem type 6 -> 512	 Activision Cart

add 1 if pokey=true

btw it should be Flags=1 is CARTRIDGE_CYCLE_STEALING (prevents maria cycle adding).

and Flags=2 is CARTRIDGE_WSYNC_MASK (prevents a wsync if the wsync flag is set).

 

Unless I got em backwards (forces as opposed to prevents).

 

Which gets me to thinking.... Hmmmm

Now if someone could just fix the couple of minor bugs in the game that would rock.

Sorry, I know this is an old thread but I din't want to create a new topic for no reason.

 

I have updated my ProSystem.dat file as instructed. However, F6 does not allow me to perform a level select in the ProSystem Emulator. Is there something else I should try?

[+Mitch]

You need to hold it down before you start a game and let go when the level you want starts.

Thanks Mitch, got it working now.
