I believe he walked up the steps to the next stage and you couldn't see him any more. Love the game thanks to everyone who made it happen.

I wonder if that will ever be fixed? It's not gamebreaking of course, but it just feels off when Thomas is not disappearing and walking into the upper screen at the end of each stage. Since we all use the Mister for that perfect accuracy

This has been reported years ago. Once again another early 80's arcade game gets ignored after its released much like donkey Kong, tron, dk3, etc. Pretty sad since the mister prides itself on its 'accuracy'. These games including kung-fu master actually work better on the raspberry pi.

This game was ported to MiSTer from another project which never claimed to be 'finished'. I suspect the author of the port is either unaware or unable to fix this issue.

mister needs a new one then. We will wait for it. Its amazing game

I had some free time this weekend so I decided to take a look at the core and see if I can figure anything out.
I came up with what I would call a hack job because I couldn't get enough information to do it the way the hardware does...even MAME does it a...different way.
While looking into the core, I also noticed that sprites were off by a few lines (really noticeable in Lode Runner) so I figured I'll tweak that too.
Attached you'll find the "test" core that you should place in your _Arcade/cores AFTER you rename your original IremM62_20230226.rbf file to something else or back it up.
This core also affects other games (Kid Niki, Battle Roads, Lode Runner....) so, if you are interested, try it out and let me know of any issues that have come up with this change. If all goes well, I'll submit a pull request and see if it gets accepted.

That would be awesome. Lode Runner is unplayable for me due to this weird offset.

Thank you

I checked Loderunner, Spelunker (had also offset) and Kung Fu Master and the two mentioned bugs are gone. Thank you very much! Finally someone who cares for golden age arcade games

can you submit the fix in order to update_all function??

I can confirm that the "ending stairs glitch" in KungFu Master is fixed.
Awesome work, Flandango!!

Thanks alot!

Thank you so much - @flandango you wouldn’t be able to also fix bombjack if you have some more free time - when you jump to the the top of the screen theres a part of his head that appears incorrectly - I have an original board and it don’t do it there

Also in Bombjack, the logo is shifted halfways.

Hi @flandango - just another thing I noticed on kung fu master is that if you have hi score saves enabled and score over 100k then the hi score in the game defaults to the original hi score of 48110 and adds a 1 in front (hence you get 148110) so effectively it never displays the correct hi score in game, but the score board on demo saves it correctly - any ideas as I’ve tried deleting the nvram - it did this before your fix too so you haven’t broke anything here

Is there a time frame when the core with the fixes will roll out over update_all?

I submitted a pull request on the core's github page so it's up to the core's developer/maintainer to accept it and release it.

It's fixed. Yipeeeeee.

Thank you for the fix!

thanks Flandango
