NFL Blitz won’t run

[loyahdev]

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

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

1. 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.

2. Copy the CHDs manually using Files.app or Start Server

It just crashes when I try to play nfl blitz now…? With all the files present

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]

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

[loyahdev]

I was able to catch these snapshots just frames before it crashed for both games

Have you tried?

[ToddLa]

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

[loyahdev]

Ok

[ToddLa]

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]

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

[ToddLa]

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....

1. You can now import CHDs and if the CHD is named romname?.chd it will be copied to correct dir.

2. 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]

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.
