Most of Easy Flash CRT do not works, but cartridge from ocean run very well.
I did not understand how to load tap files, there aren't tape commands in the core menu.

Compatibility is the same of the old core, so Pang and many other games/demos do not work as due.
Idem for audio emulation of sid in some games.

Thanks for this great new core, and hope for further imrovements :cheers:

Everything seems to work .. CRTs (standard ones ) .. disk writes, etc..

Thank you for taking the time to merge in those updates!!!

For future readers:
but I did notice the 1541 implementation doesn't seem to have the diskchange bug fix done with the C16 core (so some demoscene demos wont work as they can't sense the disk changing "Wonderland" , "We are Demo" ..) ..

the fix is actually here .. (or rather the C16 version but they both use the same 1541 vhdl if I recall)
https://github.com/mist-devel/mist-boar ... d5d6cc3aa9

- .disk_change (),
+ .disk_change ( sd_change ),

{I am posting this for historical reference incase anyone comes looking for comments about the disk change bug..)

I have been working on adding T64,CRT & TAP support to the C64 core, After getting cartridge support working i found a few problems which are fundamental to the core.

PANG, in game sprite corrupted and frozen timer.

NAVY SEALS, upon entering the 1st level moving right causes the game to reset.

This happens on both the CRT images and D64...... This is also a problem on the ZX-Uno it seems.

Please can you peeps add any "dodgy" games below in an effort to help me track down whats wrong with the core.

Many thanks, Lee

check mist/mister on Facebook I placed a file with heaps of carts for ya!

What is the likelihood of getting EasyFlash CRTs working? Simple bank switching only. I guess use of the eAPI will probably never happen (doesn't work on 1541u2)

after diving deep I think this wont just slot into the c64 core easily like cramming a square block into a triangle hole. :roll:
