Topic: Sega's 'SuperScaler' arcade hardware: realizable?

As I really liked these arcade machines back then, I'm curios, would they be realizable with the current fpga:

- (Super) Hang On
- Space Harrier
- Afterburner
- Outrun

Obviously, (Super) Hang On and Space Harrier would be the easiest of them, as they are the earliest and they share the same hardware system. However, when looking at the motherboard, I doubt that this is within a "4x Amiga 1200 Complexity" limitation...

Re: Sega's 'SuperScaler' arcade hardware: realizable?

Maybe, although it's pushing it a bit. The 68000 processor can be clocked at 2x speed and "shared" between the two subsystems.

Any schematics exist?

Re: Sega's 'SuperScaler' arcade hardware: realizable?

Schematics are available:

GPU: Sega Super Scaler chipset
Graphics chips: 315-5011 sprite line comparator, 315-5012 sprite generator,
2× 315-5049 tilemap chips, 2x 315-5107 horizontal timing control,
315-5108 vertical timing control, 315-5122 timing chip

Re: Sega's 'SuperScaler' arcade hardware: realizable?

Could be possible, just quite some work to get all customs coded. But it seems they are not too complex.
Having an actual board connected to a LA might help a lot to get the timing 100% right.

Re: Sega's 'SuperScaler' arcade hardware: realizable?

I'm definitly tempted wink
One day is a bit short to decide though, I'm still working on my personal justification to actually buy the replay hardware.

Are there more Sega Enthusiasts attending? Maybe we can somehow split the costs.

BTW, there are two versions of Super Hang On. One is probably an upgrade kit for Hang-On, using the Hang-On/Space Harrier hardware, and one is using the Out Run hardware. From googling the serial numbers of the board on ebay, I would guess this is Out Run. (Also great, but maybe a bit more ambitious...)

Did you get it? I was too late... sad
Will ask some of the dealers here in Europe what they can do...

Re: Sega's 'SuperScaler' arcade hardware: realizable?

I was very tempted - good price, but I missed it too sad

Re: Sega's 'SuperScaler' arcade hardware: realizable?

It was gone as soon as you posted the link, or I would have bought it.

Re: Sega's 'SuperScaler' arcade hardware: realizable?

Moved it here to the arcade section, as it contains some links which might be useful later on and should not get lost in the general discussion section...

I would happily donate ~EUR50 without hesitation for such a purpose, if there is a realistic chance to see results in months (not decades..)

But first things first, I will order the fpga board now.
( Maybe I will even get involved in development one day, but this is wishful thinking, I studied that stuff, but ended up as SW dev, which may sound worse than it is smile )

Re: Sega's 'SuperScaler' arcade hardware: realizable?

Meanwhile you may use the versions on the c64 or amiga setup on Replay. Oh, have to check if they work on the c64 core  wink

Re: Sega's 'SuperScaler' arcade hardware: realizable?

I will, once I have my replay board. Sega (3D game) conversions really are an interesting topic. They never reached the original, not even remotely. But than again, a totally arkward looking C64 Outrun conversion by far exceeds the ok looking Amiga version in playablility smile

"Untested" Hang On board set on ebay:

http://www.ebay.com/itm/Sega-Hang-On-Si … 35eb88627a

Auction ends tomorrow

Re: Sega's 'SuperScaler' arcade hardware: realizable?

Is somebody here bidding on this?  I hate for us all to outbid each other and increase the price unnecessarily.  Also, this is not the same as the Super Hang-on - is it still desired?

Re: Sega's 'SuperScaler' arcade hardware: realizable?

Im not bidding yet. This one is untested, which might imply some extra work. Since I cannot help there personally, I would not start bidding without further communication.

I guess, the original Hang on would be a good starting point. It is the first super scaler hardware.

There are roughly the following hardware boards:

a) Hang On / Space Harrier / Enduro racer  / a special Super Hang On version, I think
b) Out Run /Super Hang On / Turbo Out Run
c) X-Board: Afterburner, Thunder Blade and others
d) Y-Board: Power Drift and others

a) and b) share a lot of custom chips, as well as c) and d). However, the latter may really exceed the FPGAs capabilities.

Re: Sega's 'SuperScaler' arcade hardware: realizable?

If I really bid, I will tell here 10 mins in advance. Of course only at the end of the auction.

Re: Sega's 'SuperScaler' arcade hardware: realizable?

This is probably the easiest to reproduce - however in my experience untested often means bust, and that's no good for reverse engineering. Cheap though!

Before this happens, it will first exceed the possibilities to reverse engineer using non-destructive measures: checking the board schematics (if available) plus known chip functions (e.g. from emulator code/comments or any other documents/specifications if available) and looking at the pins with a logic analyzer plus oscilloscope (maybe also using some own ROM code running on the board to trigger certain functions)...

I usually still take them (if cheap enough and schematics exist), because they are often very easy and inexpensive to fix.

If not, it is always good to have some spareparts, especially if the board has several custom ICs hard to find "without board"...
