MiSTer FPGA Forum

Another enthusiastic vote for Astro Blaster! This game is seminal and I find a lot people seem to either not know of it or have forgotten about it. Gameplay totally holds up today too, it's one of my favourites... "Fighter pilots needed in sector wars"

Finally got a chance to try out this core yesterday on my MiSTer arcade cab with 27" tri-sync arcade CRT.

Amazing! Just a fantastic piece of work. Playing C64 on a real CRT is total game-changer for my enjoyment of C64 content, the low-res polygons don't age well otherwise.

Thanks Robert!

FYI I'm using this core regularly (including yesterday after updating MiSTer) with my CRT setup without issues.

Very impressive! Those scanlines look a lot better than an earlier pic that was posted in this thread. Should be black, not just a "darker shade" of the surrounding colors.

We can't be throwing away our money for each new hardware upgrade

LOL Tell Apple that.

Oh, their laptops last ages! Iphone... Well that's another thing

iPhone last forever too. SW support for like 7 + years generally. People have to complain when they change the connector type every 15 years or so. The outrage! lol.

There is a fix, go to core options and change the 68k frequency to 7.2 and the slowdown will be gone or very heavily minimized. I believe you can do this with all the Jaleco games on the MiSTer.

But that would be inauthentic!

This won't damage your CRT. You could try playing with your vertical hold adjustment on your CRT to see if you can improve things (or make them worse).

Thank-you! I always completely forget the "Alternates" section exists. You are correct, the other versions are all accounted for.

I also forgot about the annoying background music that plays continuously on the "vs" games. Unless that's a core bug, will investigate...

It appears that only the original Karate Champ core exists currently.

I was wondering if a core for Karate Champ - Player vs Player would be possible? I believe both games use the same underlying hardware.

Has anyone seen anything regarding possible development on this core?

Bump.

I tried updating again today, still no change in terms of being able to select dual joystick mode for Karate Champ.

This seemed like it was on the way, any idea what happened?

So I updated yesterday but don't see any config in the OSD for dual joystick mode. Did I miss something?

Maybe @Jotego didn't manage to include the OSD update for it.

Here is an interesting write-up on the all the quirks like that one that are present in the original arcade game:

That's awesome news! I can't wait to get my "Lunge Punch" on! What a fantastic community...

Would it be feasible to add a dual joystick input mode for Karate Champ?

This has been done nicely in the Robotron and the Rescue cores previously, as a reference.

The first-level theme music from Pirate Pete is the snizzle! Had no idea that version ever existed, very cool.

Hi retroidroid, you've made a mistake in your testing - 511 is the horizontal resolution not vertical. 240 is the number of rows.

Of course you are correct.

When the game is set to "De-Interlacer Hi-Res: On" it must be outputting 511 x 480, since it uses the 31KHz mode lacks visible scan-lines or flickering.
