Home Arcade System

I can't stop playing with it. Had to rush out a DB15 stick with an old Dreamcast case, it's absolutely amazing. Everything plays great, and connected to an XRGB the quality is insane. It's actually way better than, for say, Genesis or Super Famicom that are plagued with jailbars or parasite, here it's just pure and clean.

I love it, thanks Mike, you're lovely and your product is killer.



Also, for thoses wondering, it's going through the PS2 adapter. I have a RetroGamingCable PSX Csync cable and it doesn't work. However an old RGB PS2 cable is OK, so i guess the difference in specs from PS1 to PS2 is not compatible here (while it's ok on my PS2). Btw, as i don't know if this cable is CSYNC or Luma, will it hurt anything to be plug on the wrong sync type ? (but i guess it's fine as i'm on default CSYNC and i got the image)
 
Just a guess here, please confirm @RGB

If you were using a PS scart cable with built in sync attenuation, and the HAS has sync attenuation enabled, this might mean you're effectively double attenuating the sync line thus weakening the signal too much.

Could be as simple as setting the HAS to TTL sync and letting the PS cable solely attenuate the sync.

Not sure if that's what's going on so wait for RGB to explain it.
 
The adapter is for the PS2 Scart cables, those don't have any resistors and capacitors. Furthermore, the cable mustn't contain any sync "cleaning" circuitry.

There are capacitors in the PSX cable, so you'd need to bypass the ones on the HAS itself (there are jumpers for this) if you want to use this cable.

As far as I'm aware there are no resistors on the CSync line in both the PSX and PS2 cable, so it's not a matter of double attenuation. Unless the cable is improperly wired and it does use a resistor for some reason.

@Catzooo Cables wired for Sync on Luma won't hurt anything, but won't work unless you switch the position of the green jumper on the PS2 adapter.
 
I'd suggest HAS users may be best ordering PS2 cables as sync on luma if purchasing from RGC. This ensures no passive components in the cable.

If using RGC PS2 cables wired as csync, these contain the LM1881 and an attenuating resistor.

Good advice, I believe those are cheaper, too.

It's been a while since I checked the RGC website, but I remember they used to offer cables with "passive" sync, meaning there was no sync cleaner or resistor.
 
Hey, stupid question, but does the HAS support games that need a -5v?

The reason I ask is b/c I just bought a WWF Wrestlefest and the game works fine, inputs, colors, sound effects, but instead of music, there is horrible screeching noise. The seller claims it worked when he mailed it and I need a -5v on the JAMMA line. I'm checking the schematics of the game now to verify it needs a -5v, but I didn't see much info on the HAS to see if it supports it.

EDIT: Just checked the game, it does NOT need a -5v. I think it's just bad caps, as now the game completely lost sound. Hmm...

Need to verify that your power supply is capable of outputting it.

Thats good, I didn't see it in the instructions, and many Super Guns do not. Another reason the HAS is the best!

That being said, I have the HAPP arcade PS I linked in my thread, which only puts 5/12 to the HAS. Do I need a PS that will generate -5v? Not important for this game above, as the sound is another problem, but for future games...

Yes, you do require a power supply that is able to generate -5v for those games, since the HAS has no negatron inside.

OK, I guess that is what I'm asking. So I just unscrewed my wires to look and I see that the green wire is -5v, ah-ha! Even in the RGB instructions pictures, I couldn't see that! LOL, more info for the FAQ!
 
To the -5V rail of the PSU, just like you do for +5V, +12V and GND.

The HAS power cable has 6 wires. 2 for +5V, 2 for GND, 1 for +12V and 1 for -5V.

In short, you need a power supply that provides all three voltages, that's it.
 
how do you guys deal with boards that output stereo?
Like Konami, 1slot MVS etc.

Do you run a separate high/low converter to get to RCA?
Or could I use one of the additional header on the HAS to feed stereo to it and output via the RCA plug?
That would really tidy up the setup ;)

Sadly I don't yet as I don't fully understand it and don't want to blow anything up (speakers or otherwise), but as you guys explain it out, I'll add it to the running FAQ. Maybe soon it will be big enough to have its own thread.
 
yeah would be cool if the HAS had a 4pin stereo input header where I can feed the amplified stereo out from my boards, and let the HAS attenuate to line level for the RCA plugs.
Would that be an option @RGB?

Boards I want to run with it:
- Konami stuff, Simpsons, Xmen, Turtles etc.
- NeoGeo MVS 1 slot
- Atomiswave

CPS2 already has RCA line level out, so that's all good as it is :)
 
I wired up a car line level converter - https://www.bestbuy.com/site/metra-two-channel-line-output-converter-black/1265702.p?skuId=1265702

I actually use it on my net city now with Jammafier games. Works great once you've dialed everything in on your boards to be consistent.


As to how to wire one up you need two rca jacks you wire to the bare leads exposed. The ground wires are for isolation however I didn't need them. Plug the board into the rca jacks and then plug the HAS into the two RCA plugs on the converter. Once that's done there are two gang ports you can twist to change the attenuation.

1slot MVS all are mono (at least at the JAMMA end). The stereo ones are 2-4 and 6-slots. For those, I have a JAMMA extension (bought to RGB along with my HAS, IIRC) which has some jumpers to change it from JAMMA to MVS audio setup.
