Re: MAME SHA1 Calculation

When we add roms to the source, we use an in-house utility written in python to calculate the crc32 and sha1, and it produces formatted output which we paste into the game's rom definition. There appears to be a "sha1" library in python; the utility simply asks this library to calculate the sha1. We...

Re: NEOGEO driver frequency

Hold down Shift and Ctrl, this allows 0.1 adjustments.

So you can get to 59.986 fps

Re: Removed ROMs

I was going to suggest these might have existed in some long-ago derivative, however a search of my database returns no finds.

So, tell us where you found them.

Re: ROM Filename Case in driver

Real roms are generally in uppercase, but MAME only allows lowercase.

But in reality it doesn't matter because if the filename doesn't match then MAME uses the CRC32 hash to look for a match.

So, do whatever you want.

Re: Mame 64 .197 Killer Instinct Selecting Different Revisions Help

You are correct. There was a mistake that prevented selection of other bioses.

This has now been fixed: https://github.com/mamedev/mame/commit/ ... 5e32056664

so you can try it out in 0.198

Re: Flickering in Galaxy game (1971)

MAMEUI currently has no HLSL controls although it used to.

There's a plan over the next few months to add many missing settings to MAMEUI.

Re: Has anyone fixed the samples for Boxing Bugs?

Note that the dummy files are not supplied with MAME. They are something somebody made to keep rom managers happy.

If you can find a real Boxing Bugs, record the sounds, and make them available to the community. It's the only way to get them.

Re: IRION (Exerion) PCB found - possibly Exerion PROTOTYPE ?

OK thanks, that looks better - and it runs.

I've added it to MAME, but there;s a priority error between the ships and the landscape, I'll let another team member fix that.

Re: High scores not saving

MAMEUI doesn't yet have the settings for you to adjust. But you can get into the MAME internal UI by entering

>mameui ___empty

then doing the adjustments in the MAME way. (There's 3 underscores before empty).
