I recently got this Super Magicom 16M. Replaced the common leaky battery, and other than that works great. I even went as far as installing the missing CIC and patching the jumpers, now it boots without the need of a cart Very Happy

.

As some of you know this is a very obsolete unit compared to other copiers out there. My question is, has anyone done successfully the Hirom fix mod?. I think it requires an additional circuit or something along the lines, I'm not sure. Just want to get more compatibility going really. Any comments or suggestions?.. Thanks!

This thread covers the topic a bit:

but nobody so far has posted the PAL logic.

This archive might put you on the track Wink

^ Thanks bro!. Very Happy

Well, I just did that Hirom fix circuit mod to my SMC pcb, everything according and exactly as indicated in the op text. Unfortunately I must be missing or doing something wrong because it isn't working all the way, some games are still not loading correctly (garbled/glitched graphics)..

Here's what I got:

After the mod, the ram size display changes to 24M instead of 16M just like "Aragorn" said it would. Lowrom games still save, load, and play ok, no problems there.

I think I'm using the right complementary loader shown here, after it loads the Ram size goes back to normal= "16M" and any card size ok as well:

Now as you can see, the bios on this SMC is "V2" , maybe I need to get later version in order to work properly?.. Also, what is a manual "sram Limiting switch"?, Do I need it?.

I'm stuck, any ideas? It would be much appreciated.

Thanks again Mystic_Merlin!.

Wow, hats off for doing the mod so quickly, I guess you already had the components Wink

I believe the mod was based on V2 but here's another text file I forgot in the zip:

Hi Koji

Can you dump & upload Magicom V2 bios for me ?

I need Magicom V2 bios not CCL Bios.

I hope you can success hi-rom fix.

I also have hi-rom fixed magicom , but bios is still Procom V2 bios.

@Koji
Sorry nope, I never got the parallel transfer to work again and I stupidly damaged the PAL when I took it off but I wouldn't be suprise if the logic is identical to Aragorn's one.
Also I have another copier with that same mod still working but it's a different hardware and different bios so not sure if the logic is the same.

@Kaz
The Programmer is on its way, it's a matter of days hopefully Wink

BTW, I seem to have a fucked up bios on my SWC AdHoc, you wouldn't have dumped it by any chance? I can probably use the original SWCDX but since the AdHoc does not have any serial eprom, I don't know if it's any different?

Quick update... It WORKS!!!!....After the mod, it does indeed works!!...The files have to be sent on floppy, and you have to be sure that Hirom games are recogninsed as Hirom...

Thanks everyone!..
