- upper 8 colors are correctly updated after screen mode changing
- lpt animations work correctly (e.g. in scroll demo, antiriad or tilitoli)

what's new in version 1.11

- dave clock divider now works
- restoring dave's state on snapshot load fixed
- better video memory read/write timing
- hungarian help file

what's new in version 1.1

- 4,5 and 7 bit polynomial counter distortion on tone channels (now sound effects in "nodes of yesod" are fine)
- correct handling of very high tone generator frequencies (for games with  48k zx spectrum sounds)
- bias setting on snapshot load fixed
- fixes in soundsystem (buffer size can be smaller than 100 ms)
- programmable external joystick emulation
- new z80 timing with wait states on M1 and video memory access (this slows down the emulation a bit)
- fixes in z80 emulation. garbaged screen in chase h.q. and wec le mans gone

what's new in version 1.0

- new, optimized nick routines. for now on, ep32 runs only in 16 and 32 bit display modes. rendering became WAY (2x-5x) faster.
- ALTIND0 and ALTIND1 in character modes fixed (scrolls in cauldron display correctly)
- user interface fixes
- win98 support improved

what's new in version 1.0beta

- snapshot saving/loading (with zip support)
- directinput changes for better compatibility
- entirely rewritten keyboard handler
- keyboard setup
- non-documented nick ports are emulated (all nick registers can be reached at 84-8f  ports !!!) this way "nautilus" runs.
- external joystick emulation removed (caused many strange problems :)

- config file loader
- reorganized menus
- tape patch filename problems fixed
- invalid reqistry values are checked
- other small fixes

- screenshot saving
- tape patch is back...
- when no filename given for tape loading (e.g. with 'load "tape:"' command in basic),  the emulator will display a dialog to select a file to load
- ep32 now remembers some settings (using the registry)
- fixes in interrupt system (now 1Hz interrupt works)
- cmos clock emulation (works with zozotools)

- right DAC output fixed
- color bias fixed (still needs some tuning)
- exos nn mnemonic in deubugger
- lots of fixes in debugger and user interface
- step over for call, djnz, exos, ldir/lddr, etc. in debugger
- port i/o
- ring modulator and low pass filter on noise channel
- missing key "^" fixed
- started to work on help file
- brand new interrupt system emulation, better video interrupts, etc. now pddemo works :)
- "run to address" is back
- vertical retrace timing fixed

- disk interface now works under win9x/me
- lockup when no disk in drive under 2k/xp fixed
- floppy disk write support
- screen size changed
- pause in main menu fixed
- volume slider positon fixed
- buggy sound capture fixed
- invalid margins now display correctly

- terrible slowdowns under win9x fixed
- new disk interface. now  floppy drives on the emulated enteprise are mapped to their respective drive in your pc. so you can use your original enterprise disks on the emulator :) on nt-like operating systems (nt/2k/xp) you will need administrator privileges to use this feature. (currently it works only on 2k/xp !!!)
- some debugger fixes
- sound under pause fixed

- keyboard handler fixed (no more keyboard lockups when REM1 or REM2 is set)
