Re: Nichibutsu M68000 Based HW (Terra Cresta/Force)

https://twitter.com/_atrac17/status/1542695337810436096 Hi, I came here because of an original pcb that i am trying to fix. I was wondering if during this development the actual pcb board schematics were drawn up and/or if the 3 pals on the top board from armed formation were dumped and/or the equations extracted. My pcb is now booting and running...

Re: How Difficult Is It to Add Vertical Flip to a Core?

I concur with bazza, nothing to lose by giving it a try. However... It's certainly not the simplest way into learning core development! The level of difficulty in implementing vertical flip will vary hugely depending on the way the original hardware draws to the screen. If you are lucky and the system uses a frame buffer (like Juno First which I'm...

Re: JALECO Mega System 1 Release: 20230715 (Saint Dragon)

I have similar on my CRT. I had to force the signal to be NTSC (even though I have a PAL TV) in order to get a stable picture. I'm not near my Mister at the moment, but I'll try and find out the key strokes to enable that next time I am (there's an H/V offset that had a similar effect for me). not sure what the issue is,runs perfectly on my Sony C...

Re: JALECO Mega System 1 Release: 20230715 (Saint Dragon)

Thanks for the update! However, this latest update has "broken" Rod-Land for me, and P47 doesn't work either, since they're now losing sync (or something similar to that). Like a sync or resolution change where the HDMI screen has to find the right sync/mode/resolution. Before this update Rod-Land worked fine (apart from occasional slowd...

Are you planning to recreate any PRE Mega System 1 games from Jaleco? Like 1985's City Connection..

Yes and no. City Connection wasn't on my to do list. Only two other JALECO games and they are extremely rare/expensive.

Re: Data East's RoboCop 2 Announcement

Off topic but thanks to this I found out about the USB2DB15 encoder. I wanted a solution for using USB controllers on a super gun a couple of years now, I was going to try to make it happen with a chinese micro that has USB host but never really got to it. Excellent to see I don't have to. 10/10 recommend. I have spares that would have been built ...

@Atrac i have a broken board "Crude Busters" if it helps i would like to donate it to you. So what is broken - one of the data east chips is soldered off and a few broken pcb traces in that area. Before that it worked flawless only the blue color was missing.

Send me a PM. I might take you up on it.

Great job, one of my faves.

Found a small error/bug in Fire Shark (fireshrk) I think:

Setting continue game to "no" has no effect, the game still accepts continues and has a grace/waiting period before you can restart.

That is a bug, but I think it's an actual software bug. I'll have to look again. Don't really remember.

Re: Zero Wing by Toaplan Arcade Core Released

DIP settings for (Out Zone) and (Truxton - Tatsujin) main mra's does not seem to be working after latest update. Games remain in Japan region no matter what is set in DIP I've fixed the issue. It's because I refactored the ports like the PCB and didn't check the bit's in the MRA files that I generated from MAME. They use different mapping on the I...

For all of those who had issues or wanted QOL like "60Hz" it's done. The remaining games from the hardware will be separate repositories. Demon's World, Rally Bike, Vimana/Same(3x) will be released soon! Enjoy.

Re: JALECO Mega System 1 Release: 20230715 (Saint Dragon)

Check out the readme, CRT's should sync to the native refresh rate toggle as I have the hardware now. Timings were inaccurately reported in mame. This is why hardware is an important part of the development process! Enjoy!

So... are there two cores that play Rod Land now?

Correct. Pierco has his own that is unfinished and gave us the greenlight as we wanted to do the whole platform. More info in this thread.

Re: JALECO Mega System 1 Release: 20230715 (Saint Dragon)

It's dependent upon CRT for the sync. I made the toggle for ease of use until I pull the actually values off the board for sync width etc.

Don't mind the geometry, it's intentional and has nothing to do with the core.
