NFL Blitz won’t run #357

Open loyahdev opened 2 years ago

loyahdev commented 2 years ago

I have the chd file but it won’t work like I don’t know where to put it any help?

ToddLa commented 2 years ago

The CHDs needs to be in a subdir of roms matching the romset name.

In your case roms/blitz

You can do that in a few ways

Put the CHDs in a ZIP file named blitz.zip (or inside a ZIP with the path name blitz/file.chd) and import that ZIP into MAME4iOS.
Copy the CHDs manually using Files.app or Start Server

It just crashed for me with both of these

I will see if I can get Blitz to run, might just be a MAME issue

Gotcha

loyahdev commented 2 years ago

Would it be the same as street fighter 3 and that chd?

loyahdev commented 2 years ago

I was able to catch these snapshots just frames before it crashed for both games C2D3D08C-C316-4599-8DCB-3CB259AC030C 6CF1E0C7-F62F-490A-991A-9589F74C01C4

Have you tried?

ToddLa commented 2 years ago

Not yet, tomorrow, first task is to verify it works in the command line MAME first....

I got blitz to run

had to do a manual import of the CHD (will add special CHD import....)
CHD format not supported on 139, had to use 2xx
it ran, BUTTT just got a black screen and was unable to exit. ie it did not crash.
NOTE also does the same thing on the CLI build of MAME, have not tried intel yet, but I bet it works.

Sounds like a DRC on arm64 issue.

loyahdev commented 2 years ago

rough hope it eventually works but can you tell me how to in some sort of a simpler way if possible?

ToddLa commented 2 years ago

Yea this is a arm64 DRC issue in the MAME core, surprised that they don't test C based DRC for non-intel. I don't fully understand. But would effect many platforms, so I don't get it. This can't be broken across the board can it?

Two things in 2021.8 help this issue....

You can now import CHDs and if the CHD is named romname?.chd it will be copied to correct dir.
There is now a Setting called Use DRC and it is off by default. This makes NFL Blitz run without crashing, but it is too slow to play 😥

You got it to work?! For me 1 and 2 don’t work when I import the chd with blitz?.chd it doesn’t work even without the “?”. It doesn’t work either. Even with the DRC setting on it still crashes.

ToddLa commented 2 years ago

I don't mean put a "?" In the filename!!

Just import blitz.chd and it will get copied to the right place, so will blitz1.chd, blitz2.chd, blitzq.chd

That is all blitz?.chd means, ? Can be any character.
