5 more: 
Encounter
Spindizzy Worlds
Thunderhawk AH73M  (good PMMU code solves problems caused by only on TT harmful bugs , and not only here)
Outrun
Jim Power

What comes next is:  early test versions of few games, for Falcon, TT, with PMMU used for RAM area swap. Should be compatible with all decent hard disk drivers, larger disk caches. There will be library files for common functions, what will save some diskspace and make updates easier , also coding game launchers faster, simpler. I gradually went on more and more library functions by time, and now see that WHDLoad is based on it.  Sources will be published with instructions (when reaches some mature state) ... Will someone try to do game adapt self with it ?  :)

OK, it works !  I mean, PMMU based RAM area swap on TT and Falcon - very fast.
I made 2 YouTube videos for demonstrating difference between classic SW swap and PMMU swap.
Both is made on Falcon, with Hddriver 8.23 taking a lot of RAM, 1GB partition means 20x16KB=320KB only for sector buffers, by default.
Totally about 900 KB TOS workspace must be moved before and after every disk access. But PMMU does it in few microseconds.

Here is for testing:   http://atari.8bitchip.info/HAGAT.ZIP

Game is Fire and Ice . Updates are mostly interesting for Falcon and TT users. With not my hard disk drivers . Feedback is welcome and will be used for further development.  Read suplied TXT file in archive.

Will do some other games for next week - need to find some with lot of disk access  :)

Forget what wrote here about DMA bugs. I fixed problem. Added exit to Desktop too, and Dragon's Lair  .

 http://atari.8bitchip.info/SPACACHA.ZIP         http://atari.8bitchip.info/DRAGLAHA.ZIP

It works with 1MB machines too, with barely visible loads during play (read ahead cache). With 2MB or more TT, and 4MB Falcon or more.
Any hard disk driver AHDI compliant.

Next step:     http://atari.8bitchip.info/SCRSH/chuckr.html (http://atari.8bitchip.info/SCRSH/chuckr.html)

+ another stone age game:    http://atari.8bitchip.info/BIGNOSE.ZIP (http://atari.8bitchip.info/BIGNOSE.ZIP)

Savestates: worked on in last days - autoincrement, possible to add comments and read them form statesave files - without extra SW.
As it is executable. Doubleclick:  straight to saved pos in 2 secs. Doubleclick with Shift held down: show HW on which made + comments, or other Shift held down: Enter comments.
