Does anyone own a ropeman? This is a bootleg RocNRope.... I would be interested to know what they used to replace the Konami Customs.

If you own one and high Res photos would be appreciated.

Thanks in advance

My boardset is slightly different. It has the same top board but the bottom board uses a daughterboard which contains the 6809, 2 PALs and 6 logic ICs (1xLS04, 2xLS74, 1xLS244, 1xLS245 & 1xLS374).

I too have a bootleg Roc n Rope. The only daughterboard custom replacement is the Konami 1. In fact, I leant it to myPinballs last year, part of this thread. https://www.ukvac.com/forum/threads/help-needed-from-gyruss-bootleg-owners.76026/ . Happy to dig it out again and take a proper photo if you still need it.
Interestingly, the bootleg daughterboard is 42 pin and works in the the genuine Konami boards I've tried it on.

OK... back from hols now...

I'm not that interested in the Konami-1; I think that is pretty well understood. I'm just interested in the 083 implementation on THIS board.

If anyone has a broken ropeman and would like it fixed... I would be interested in helping you (and learning the implementation along the way).

I think I can see some 74LS194s in there... I think 4 of them make up the 083 replacement.... there is also another 083 implemented on the extra row on the other edge of the board...

Again a flat on shot of that area would be appreciated.

Very good. Thanks for doing that...

I'm going to guess this is the 083.

which matches something I drew 5 years ago...

Quite interesting. Might have to add a ropeman to my collection at some point as it implements 502, 503, 082 and 083 customs (at least partially).

In case anybody is interested, I dug out my board earlier and did a de-bootleg (almost).
Swapping ROM7 @ J12 for the Konami ROM7 @ H12 gets rid of the ugly title screen and a few seconds of hex editing on ROM1 @ J1 gets the Konami copyright back.
Replacing ROM6 with the Konami ROM6 caused graphics issues and replacing ROM1 with the Konami ROM1 caused the game to stop booting.

That's interesting. I wonder what the difference in functionality is. Looking at the difference it looks like the Copyright has changed "KONAMI 1983" to " 1 9 8 3 " but otherwise there is only a 2 byte difference... 023E F6->00, 0326 09->00

TBH I'm surprised it doesn't run.

PS
Looks like the first mod disables the VRAM check at reset and the second mod disables the "OBJ 2" check at reset.

When I had the Konami ROM1 in place I tried combinations of bootleg and original ROMs 6 & 7.
During these tests I was getting an OBJ 2 error or static garbage.
It only worked properly with the edited bootleg ROM1.
