I have just released a new MiSTer FPGA Arcade Core for the 1983 game 'Exerion'.
Two months ago I challenged myself to write a FPGA core as it was fascinating to me. I'm proud to say the source code, KiCAD schematics and executable files can be found at... https://github.com/antongale/EXERION/re ... ag/Release
I documented my progress at https://twitter.com/antongale

I had a love/hate relationship with the cocktail version of this game back in the day. The floaty controls drove me nuts! ...but it keeps you coming back for sure.
What kind of technical background do you have that you felt like you could take this on? Just curious.
Thanks a bunch.

Thank you so much for this release! I've been eagerly anticipating it since I first saw you tweeting about it.
Please allow me to attach a slightly edited .mra, so that the core can make use of the merged romset (sorry, can't post a PR on Github):

Hello! Has anyone managed to star the core? I am using update 2.0 but it does not download the zip.rom. I found exeriont.zip but when I load the core it will always say prom6.4s is missing even though it is definitely in the rom folder. Has it it got something to do with merged or split romset? In the mra file of exerion there is also a prom 5.4p but when mister loads the core it does not say its missing.
Can someone help me please what is wrong
regards

Provvisorily I took the three unmerged mame sets I have from mame folder and put them in one zip and it works
PS: you have to name the romset as "exerion.zip"

Hi, for now just look for the merged rom and use the edited version of the .MRA kindly provided by @lamarax.

Yeah,
xterc may want to look at implementing flip-screen, as well as the latest framework.

I will add flip screen soon.
I have found an issue that needs an additional patch line in the MRA file to circumvent a protection check.
If there is an entry in the 17th slot of the hi-score table the game goes into a continue loop. This was encountered at the Houston Area Expo and is patched here. I will update the GitHub tomorrow.
I normally post updates on Twitter (@antongale).
