ANNOUNCEMENT - MMS1 - A 16 in 1 MULTI FOR JALECO MEGASYSTEM1(A) FROM CAIUS + HAMMY

Easy to fix , just a pain in the ass!
Just had one of these get busted in shipping, very common problem on this motherboard :(

List updated, still a few to post
Royal mail was hacked in january and has only just started to accept international stuff again.
If it's not one bad luck it's another!!

As you can see it is a 2PCB set - Standard romboard + PROM board (connected with a ribbon)
Very easy to install, the same as a regular game. (Hammy said "regular" game when he reffered on P:47 or other TYPE "A" released title)

https://jaleco.fandom.com/wiki/Jaleco_Mega_System_1 -> for those who want a donor , "TYPE A" released titles are the donors you're looking for !

@Brakvader

If you want to use BIG Striker , Cybattler (these are TYPE C) , etc. or other than "TYPE A" as donor , you simply cant . You don't have where to connect the Multi board . I have in my collection (look here) this title and isnt good donor for multi !

BIG STRIKER = NO GOOD DONOR "Type C" looks like this

GOOD DONOR : "Type A" released titles looks like this

If anyone has a Type C board and would like a Type A as a donor for this multi let me know. I have a spare Type A (not for sale but would trade for a Type C).
 
Re- added the full objects (nops / 4e71's after the red "80" not required / put back to normal) and there's no flickering sprites at all.
Very happy to get to the bottom of this one :)

Basically it needed a slap each time BEFORE a sprite ram operation happens, the object number was not the problem in the end.
I guess the double clear could be reduced to a single clear now but the extra nanoseconds of boot time can stay as a reminder of the bad times. ;)

What do I have to do get the fix ? Could someone point me to a location with the newest file(s) to burn? thank you

Games looking great but i still feel the devs shoulda had some kinda bg music.

The original has music but it's on YM2203 (we have YM2151 on the MS1)
It needs to go through a conversion , and it's not my area of expertise.

Hopefully a tool such as this will gain YM2151 support sometime:

It's a shame there's not enough sound chip guys these days , it's specialist stuff.
