If you wish so, you may then relocate the ZXDS.nds (supports [[DLDI|DLDI]]) to elsewhere on the card, like to the root itself, to make it more accessible.

'''Note from developers:'''
'''Note from developer:'''


The provided binary ZXDS.nds is primarily intended for Slot-1 (DS slot) based cards. Most of these cards now support automatic [[DLDI|DLDI]] patching, so you likely won't have to bother with that at all. Just give it a try and you will see. If it won't work for you right away (meaning you won't be able to see any files to load in the load requester) you might need to patch it with a specific [[DLDI driver for your card with a DLDI patcher, both of which you can find here. The ZXDS.ds.gba version which is better suited for Slot-2 (GBA slot) based cards, and will likely need to [[DLDI|DLDI]] patch it first in this case.

==Changelog==
==Changelog==
'''1.0.0 1.7.2012'''
'''1.3.4 2017/04/23'''
* HALT is now correctly contended by PC+1, not PC.
* To give the user a clue, incompatible multiplayer peer is now detected and reported, if possible.
* Happy birthday, Speccy.
 
'''1.3.3 2014/12/24'''
* Upon startup, let Start show the most recent files only if there are any.
* Properly handle save slot medium if all ten medium slots are still being used.
* When statistics become full, don't discard entries which might still be part of the recent list.
* When global statistics are loaded, pick the latest version under all circumstances.
 
'''1.3.2 2014/11/22'''
* Fixed libfat bug which could make corrupt directory entry after the last entry was deleted. You might have experienced this mostly when renaming files or moving them around.
* Fixed couple more libfat bugs (really long names, alias creation, whitespace trimming).
* Added caseinfo extension to libfat so letter case of 8.3 names is now read properly.
* Medium associated with persistent copy of save slot 0 is never deleted prematurely anymore.
* Save slot medium removal is now postponed to further improve chance of media reuse.
* Few other subtle changes (cache filenames, file name trimming, minor help tweaks).
 
'''1.3.1 2014/07/10'''
* Fix the initial main screen palette which could get messed up on some cards.
* Make the mouse help window look like all the other help windows.
 
'''1.3.0 2014/07/01'''
* ULA+ emulation for all Sinclair and Amstrad models.
* Support for all types of 3.5" double sided +3DOS disks.
* Raw screenshots now support the ULA+ extension for both saving and loading.
* Current ULA+ palette can be changed simply by loading the appropriate ULA+ palette tape files.
* Other ULA+ related changes (BMP screenshots, thumbnails, SZX support).
* The selected ULA mode as well as the display mode are now part of the config file.
* You can now keep your desired custom configuration persistent separately in custom.cfg.
* Sector viewer now displays bottom side track addressing info in inverse colors.
* Reverted special treatment of full size TR-DOS disks, so padded images work again.
* Minor +3DOS fixes (gap3 reading, EDSK track padding, SZX disk side selection, motor bit disabling)
* Loading a POK file now automatically shows the poke screen. Pressing Y switches back, as usual.
* Reading attributes from unmapped ports on Pentagon now mimics the real hardware mod behavior.
* Other subtle emulation accuracy improvements (+2A/+3/Pentagon screen timing, 128K/+2 INT duration).
* Many internal changes (optimized screen sampling, optimized contention, async palette switching).
* Other subtle changes (UNDO media keeping, CPU stepping prior snapshot save, volume mode order).
* Minor bugfixes (media slot release, paths set to root dir, filter in root dir, allowed filter chars).
* Happy birthday, and thanks for all the fish.
 
'''1.2.0 2014/02/19'''
* Proper Spectrum +2/+2A/+3 emulation, including contention and everything.
* Support for +3DOS 3" DSK/EDSK disks, including formatting, autoboot and disk browser.
* TR-DOS formatting now also works for all possible disk format types.
* File and directory name filtering is now available in file requester.
* All keyboard keys are now sticky whenever the emulation is paused.
* In load requester, L/R+Y now shows the other medium than Y does.
* Button input in file viewer can be now toggled with icon or L/R+X and Pause.
* Full size TR-DOS disks are now always treated as double track and double sided.
* Alternate save/load directories now work better and even with filter enabled.
* Various internal changes (ROM deltas, SZX +3DOS support, plus model stats, media icon).
* Minor bugfixes (FTP files caching, hex decoding, TR-DOS BASIC start line).
* Dedicated to my beloved parents. Thanks for getting me my first Speccy.
 
'''1.1.1 2012/12/24'''
* Spectrum +2A/+3 snapshots are not rejected right away anymore. Instead, they are executed in 128K mode with extended paging enabled. This makes some +2A/+3 RZXs and exclusive software work quite fine.
* Added a bit of color coding to the controls screen.
 
'''1.1.0 2012/12/20'''
* Custom ROMs support. See roms/readme.txt for more info.
* IF2 ROMs and 48k/128k ROMs can be loaded directly in load requester.
* Both SZX and Z80 snapshots now support custom ROMs as well.
* TR-DOS/Beta Disk support for all models, not only Pentagon. Simply choose the model or reset the machine while a disk is loaded. You can also autoboot any disk with current model by using R+A.
* Beta 128 in 48k mode responds even to the standard Beta 48 entry points. This makes both Beta 128 and many Beta 48 programs work at the same time.
* True Beta 48 mode can be enabled with proper beta48.rom (such as TK90X's CBI95 ROM).
+ Added NMI aka Magic button - becomes useful with some custom ROMs.
+ Added custom keyboards for more games as well as one for more comfortable text typing.
+ Added Virtual TR-DOS games and ZX AAA demos sites to servers.cfg.
* Pressing Start twice upon startup now takes you to the last used files view.
* Few subtle changes (save slot media loading, ROM launch stats).
* Little optimizations (Z80 core, sound generation, normal speed load mode).
* Subtle emulation improvements (authentic SCF/CCF, MEMPTR and AY white noise).
* Minor bugfixes (grayscale border, step direction bit).
* Merry Christmas.
