Released: MK2 for Wolf Unit boards

[Asure]

After my port of NBA JAM TE/SE

Thread 'Released: NBA JAM TE/SE For (any) Midway Wolf unit boards port Milestone 1'

Oct 2, 2024

I have decided to release this in the current state, as i keep postponing it because of time issues, or i get lost in writing more documentation.
(My backlog is also insanely full, i need to pick projects carefully.)

So here it is: A port from source of NBA Jam TE/SE aka the 5.0 Griffey release.

It's a full port of the T-Unit code into W-Unit (which is very similar, but not quite.)
A lot of time and work went into this. I started back around Christmas 2023, so it's almost a year of work, reverse engineering, fixing up code, (back/forward)porting of stuff from Hangtime and so on.

A lot...

I'll need testers on real hardware please. @Darksoft pls sticky

What's new:
========
- Based on Revision 3.0 with minor changes (no other src leak).
- It's missing the code for sliding down the spikes in the stage fatal.
- All hardware i/o / DMA2 / protection / DCS / CMOS stuff remapped.
- Dip / PAL/SCRATCH/GFX RAM tests etc fixed.
- Individual stuff like select screen/diag/game inputs fixed.
- Rebuilt DCS audio for Wolf boards / 4x 8Mbit chips
- Show endings in test menu added. (for debug)
- Deprotected, it should run even w/o PIC, please test.

That doesn't seem like a lot of changes but it took 2 years to get here.

Stuff left todo:
==========
- Board pics in diag mode.
- ROM crc tests
- Double check dips
- Some day, backport L3.1 / L3.2 changes/fixes
- Someone please test this on real hardware!!

Notes
====
If anything is upgraded from the todo list, this will just be a 2-rom reburn, gfx and sound remains the same between all MK2 revisions.

Awesome news mate, great work and thanks for releasing!

 

[Darksoft]

Fantastic job!! Thread sticked. I can't wait to hear the feedback on these.

I have had zero reports of anyone trying to run this on real hardware, if you have a MK2 single 8MB rom board, you can simply drop in the GFX roms on a Wolf unit and save a lot of time. I don't have one though

 

[Darksoft]

Come on people! We need some testers!!! This is for us to enjoy!

Ah! good that you figured this one out! Does this translate back to the T unit also?

I'm surprised nobody has tested this yet! I would of given it a spin but not setup at the moment

I have a Hangtime board…

May I purchase ROMs from someone? I understand the risk of it being a test release
