I tried emulating PC engine or turbografx game (Castlevania Rondo of Blood (J) English translated version) on mednafen. I was not successful despite all of the best efforts on my behalf. I read the tutorial on how to emulate with mednafen (with GUI add-on), also did read official help from the mednafen itself, searched youtube for error message's fixes but all in vain.
I was getting Generic error "This Gui version is incompatible with earlier versions of mednafen 0.9.xx, update it". After updating, I was consistently receiving the same error. So were was the glitch? I continued working over the mednafen and ultimately fixed it.
Fix: Download the mednafen zip from fantasyanime. In downloaded zip all contents are okay except one i.e. mednafen.exe . The provided medgui version is not compatible with that mednafen version. Replace the mednafen version to 0.9.28-WIP as referenced by medgui helpme.txt inside same zip.

Conclusion: I used brain, spent time (in sessions) to reach the roots of issue and fixed it!
