====
- when used on 16kB 600XL with EXTMEM enabled, it tries to expand it to 64kB
  base RAM (if enough cart ram is free)
- changed key autorepeat delay/rate
- some fixes related to EXTMEM

0026
====

0025
====
- EXTMEM tweak (not all SRAM chips are made equal)

0024
====
- PDS/COV/COS files run PDSPLAY/COVPLAY/COSPLAY
- added ability to select (TAB) CAR files
- selected files (ATR, CAS, CAR) don't have to be in the same directory
  anymore, selection is cleared only after returning to the selector
- ENTER on ATR/CAS/CAR file will replace the selection so SPACE was added
  to run with selected files, ignoring current file under cursor
- search now allows navigation during searching and editing search string
- CTRL-L disables item shortcuts and allows starting search by typing
  instead of '/'
- ESC stops search, exiting search requires 2x ESC (to prevent accidental
  exit when search stops at the same time user tries to stop it)
- disable cart was changed to SHIFT-ESC
- short filenames should finally (hopefully) have proper case
- filenames longer than screen width should be (finally) properly sorted 
- type 57 (2kB) fixed
- right cart button will disable cart for carts <= 16kB (to make some
  CS turbo carts work)

New keys:

SPACE - run selected files (ignores item under cursor)
CTRL-L - toggle key shortcuts

Changed keys:

ESC -> SHIFT-ESC (disable cart and reboot)

0023
====
- [ECI] Auto-enable cart menu after reset (CTRL-SHIFT-E to enable, CTRL-E to
  disable)
- [ECI] Patched OS for ATR emulation is forced as ROM, not just loaded into RAM
  under ROM, increases compatibility
- [ECI+SIO] When emulating ATR, HSIO patched OS with inverted OPTION (BASIC
  off) is forced

0022
====
- [ECI] EXTMEM support up to 512kB (CTRL-SHIFT-M to enable, CTRL-M to
  disable)

0021
====
- XEX loader now doesn't occupy $0800 page
- ATR/ATX emulation fixes (Bruce Lee, Ultima, Flight Sim II)

- Show COM/EXE files in browser
- Increased limit of virtual drives to 8 (SIO)
- Autorun key changed from 'A' to 'N' due to issues with PS/2 adapters
- Added saving facility (used by FloB)
- Stacking SpartaDOSX with another CAR (CTRL-SHIFT-RETURN)

0020
====
- Support for optional SIO cable (ATR, ATX, CAS)
- Copy/delete file, template dir
- Autorun redone, added setting shortcuts
- OSXEX renamed to OSXEX2 due to incompatible change (use the one from the update zip)

0018
====
- Run AUTORUN.(CAR|XEX|AVF) on power-on if present in /_AVGCART/ directory
- Added type 44 (OSS 8 KB cartridge)
- Added type 53 (Low bank 8 KB cartridge)
- Added types 54, 55, 56 (SIC!)
- Fix bank reenabling for some OSS carts
- Fix cursor position after running file from search results
- ESC exits search results instead of disabling cart
- Cart initialization speedup to remove the need to manually reset the machine upon power-on on certain configurations (e.g. QMEG OS)

0017
====
- Fix CAR command in s2sdx3.car

0016
====
- Fix for Gremlins (http://a8.fandal.cz/detail.php?files_id=1977)
- Fix for Green Beret (http://a8.fandal.cz/detail.php?files_id=1974)
- SIDE mode on power-on if right button is pressed
- SIDE mode on power-on if card contains file _AVGCART/SIDE (Ctrl-Shift-S and Ctrl-S creates/removes file on card)
- Shift-S is now working for cards with no FAT filesystem
- Right button in SIDE mode emulates SIDE button

0015
====
- Joystick support

0014
====
- ATR files are now writable and can be cycled using right button (use TAB for assignment)

- added search ('/')
- fixed issue with 'L' key
- fix for SDX disable

0013
====
- IDE emulation improvements and slight speedup

0012

0011
====
- IDE emulation (read-only)

0010
====
- XEX loader fixes

0009
====
- fixed metastability issue affecting file selector
- fixed possible out of bounds access in file selector

0008
====
- fixed issue with some files not showing up in file selector
- fix for type 42 ((Atarimax 1 MB Flash cartridge) - select last bank as initial
- refactored VHDL code to get rid of various kludges and hopefully also some timing issues

0007
====
- XEX loader tweaks

0006
====
- added type 18 (Bounty Bob Strikes Back 40 KB cartridge)
- added type 43 (SpartaDOS X 128 KB cartridge)
