In The Hunt port coming to NeoGeo?

[GarouSP]

the simplest way is to use a progBK2 which accepts 4MB 27c322 for audio.

Solutions:
1) ProgBK2
2) Toshiba adapter
3) Bank switching

no other way to use SNK board.

What about jumpers on PROGBK2?

PROGBK2 board looks like it is used by some rarer games. A more common board can't be used?

2001 has PROGBK2, I think that to use other boards its necessary to do bankswitch...

for audio JV16+JV14+JV9+JV12
JV5+JV7
JU1+JU2+JU3+JVU1+JVU3
J4+JV2

Yes, follow the image for bankswitch on progbk1 or use adapter

This is how can be splitted:

Split C1 and C2 in 2MB part and keep only the first 3...

Use C1 splitted as C1-C3-C5 and C2 as C2-C4-C6

For C Rom, can I use 3 27C322? instead of 6 27C160?
PS: I think that I making a mistake here, when splitting C Rom it'll be 4 parts of 2mb and I need just the 3 first parts of it, I guees that I can't use 27C322

 

[pierpa86]

Yes sure,

Sure you can use but you got empty space inside. No problem its still working fine.
You can use 4x 322 or 2 322 and 2 160

Oooh this is so nice - loving to see @ack s amazing work one the Toshiba adapters come to life.

Question if I may, looks like there are 4 x VROMS on the BK1. would it be possible to consolidate to just 2 x VROMS with 640's on the flash adapters or the like?

I think its not supported on progbk1, but good question.
i never see an 8mb as v rom

 

[nnap]

I love those @ack adapters. Had the backside populated by JLC so I just had to put on the flash memory.
Is there a flash adapter that supports 640s? If so that would be interesting for other stuff like PGM and Capcom ZN-2.

its supported on adapter and word mode, but on progbk1 i think no.
You can use this adater to replace 8MB mask rom. (word mode) on CHA512
I think it should work as 8MB byte mode because Byte pin is the same on MX29LV320E and MX29LV640E.
But i think its not work on progbk1.

 

[LittleLarrySellers]

@pierpa86 - I am close! I used a CHA512Y board with the PROGBK2 and I have sound and I can see the timer and static graphics and the game loads and is playable so I believe that means all the ROMs are working except the C? I think maybe the jumpers are wrong? I searched for CHA512Y jumper settings and tried both that I saw but no luck. Any advice? Thanks!

 

[pierpa86]

Nice work, it’s mean problem with c rom yes, you have splitted in 6 part c rom so you are using 27c 160 ? They are not compatible with cha512y. You need 27c322 and split c rom in 4 or use cha256 with 27c160 using 2mb part.

 

[LittleLarrySellers]

Yeah i split 6 ways and used 27c160. Didn't realize these weren't compatible with the cha512y. I'll see if I have a 256 board, if not I'll do the 4 split. Thanks for the tip.

 

[LittleLarrySellers]

You know what sucks worse than desoldering all the C roms? Doing it twice!

Lesson learned though and now with the 4 27C322 approach the graphics are working on my CHA512Y!! Thanks @pierpa86

Now that I can finally play the game, I noticed one last issue. There is a clicking/static noise. There were no Z80 error or anything so wondering why the audio is doing this.

Here is the current board and jumpers. Is there anything else I am missing?

Check this jumpers,
Red circle should be empty - nojumper
Move R6 to R3
All other is ok.
