-- -- -- -- -- -- Home Download Screenshots Tech info Support Links Forum   -- Home Download Screenshots Tech info FAQ Links Forum Blog Dualis is a plugin-based DS emulator for x86/Win32 computers. It is written in x86 assembly and C++. Important information: Dualis is not able to run dumps of NDS cartridges. Do not ask me if/when it will be able to run said dumps. Also, do not ask me how/where to get non-public material concerning the DS. If you didn't understand the last three sentences then get the f*** out. Thanks. 2007-05-27 CPU: Fixed a bug in the division SWI CPU: Improved IRQ handling a bit CPU: Added emulation of GetCrc16, GetSineTable, GetPitchTable and GetVolumeTable GPU: Fixed a bug in the backdrop color selection that would sometimes occur GPU: Fixed a bug in the rendering of 256-color r/s BGs (mode 4) GPU: Modfied palette offset calculation for 256-color textures GUI: Fixed a bug where the emulator would occationally freeze for a couple of seconds GUI: Fixed a bug where CFlash initialization would sometimes fail when loading a ROM through the File menu GUI: CFlash emulation is now automatically disabled when a compressed ROM is loaded (.zip/.7z) GUI: Added a dummy sound emulation mode that works on computers with no DirectSound (EmulateSound=2 in dualis.ini) GUI: Fixed a bug related to loading a ROM by double-clicking it in explorer GUI: Added a "Recent" menu GUI: Fixed some bugs in the map viewer MMU: Fixed an LZ77 decompression bug The full source of emulator is available (I use VS2005, but VS6 might also work), so if you're unhappy about some feature that is missing/broken, feel free to fix it yourself. 2006-05-03 CPU: Fixed a bug in the division SWI GPU: Fixed some tile flipping bugs GPU: Optimized rendering of extended palette BGs a bit GPU: Disabled rendering of OBJ windows MMU: The FAT is now writeable INP: The keyboard layout can now be configured in dualis.ini GUI: Improved the texture viewer FAT write operations are fairly restricted at this point, see the README section on GBAMP emulation for more details. 2006-04-30 CPU: Fixed updates of some function pointers after changing the ITCM size MMU: Added support for send FIFO flushing MMU: Added support for send FIFO empty IRQs MMU: Added support for IPCSYNC IRQs MMU: Fixed a bug in the handling of FAT long filename entries MMU: Fixed some bugs in the FAT emulation that would occur if a directory contained more than 256 directory entries GUI: Modified CPU synchronization 2006-04-21 GPU: Fixed some texture transparency problems GPU: Fixed some bugs when rendering 16-color rotoscale OBJs GPU: Fixed some bugs when rendering extended palette rotoscale BGs MMU: Added experimental SPI touchscreen handling MMU: Fixed some bugs in the handling of long filenames in the FAT GUI: Improved timer event handling a bit GUI: Fixed .zip loading GUI: Added support for .7z loading The SPI touchscreen handling is not perfect yet and only works somewhat, so the old faked method is still used as a fallback for homebrew ROMs using libnds. 2006-04-13 CPU: Fixed some problems with mode changes after SUBS CPU: Fixed some problems with SWI 6 CPU: Fixed some problems with address writeback for LDM instructions CPU: Modified interrupt return address handling a bit CPU: Added a few missing LDM/STM instructions CPU: Added the Thumb BLX instructions GPU: Fixed alpha blending for extended palette BGs GPU: Added the possibility to turn off 3D emulation APU: Added support for ADPCM audio MMU: Fixed some destination address control bugs in DMA transfers MMU: Fixed some problems with the IPC FIFO MMU: Added support for IPC FIFO interrupts MMU: Added support for virtual ITCM resizing (up to 32 MB) MMU: Added support for 64bit/64bit->64bit operations to the hardware divider GUI: Fixed some problems with the keyboard shortcuts when using the debugging windows When running the demos from E3 2005 you should generally use the GDI renderer and disable 3D emulation in the video settings. It should also be noted that touchscreen input does not work in those demos at this point. 2006-03-28 GPU: Added support for the A3I5 and A5I3 texture formats GPU: Fixed some errors in color selection for paletted textures MMU: Upped the FAT limits to max 32768 files/directories with a total size of 256 MB MMU: Added support for long filenames in the FAT GUI: GBAMP emulation can be turned off (on memory tab, or in dualis.ini) GUI: Switched from WM_TIMER to a multimedia timer callback Note that the max number of directory entries at the root level still is 512, and that the max total number of files/directories will be lower than 32768 if there are files that uses long filenames. 2006-03-24 *Update: The original version of Dualis 19 would freeze if you loaded a ROM by double-clicking it in explorer. This should now be fixed. CPU: Added the LZ77UnCompVram SWI (callbacks are ignored) APU: Added support for PSG noise MMU: Fixed a problem with the IRQ flags sometimes being set when they shouldn't be MMU: Added some support for ATAPI and FAT16 (GBAMP) GUI: Screenshots are saved in the same directory as the ROM file GUI: Various small changes to allow the FAT emulation to work Some current limitations of the FAT emulation: Only read operations are supported, max number of files/directories: 256, max combined file size: 32 MB, only 8.3 format filenames. 2006-03-20 CPU: Added the LZ77UnCompWram SWI CPU: Fixed a typo in the SWI 3 emulation that caused single cycle waits GPU: Added the option to display only one of the DS' screens (useful in fullscreen mode if only one of the screens are used) GPU: Added support for texture alpha bits (for 16-bit textures) APU: Optimized the resampling filter a bit, and applied filter to PCM16 samples as well APU: Added PSG emulation (rectangle waves only) GUI: Added fullscreen support (toggle with Alt+Return) GUI: Added a couple more registers to the I/O register viewers The preferred fullscreen resolution can be specified in dualis.ini. Some new keyboards shortcuts have been added: Ctrl+Shift+1..Ctrl+Shift+3 to select which of the screens are displayed, and Ctrl+Shift+F to toggle on-screen fps display while in fullscreen mode. I've also written a little PSG demo that plays 3-channel rectangle wave music - you can find it here . 2006-03-17 CPU: Modified the code for SWI 3-6 a bit APU: Reduced sound latency. If this causes problems on slower computers you can enable a larger buffer in dualis.ini APU: Corrected sound looping in most cases APU: Improved resampling quality a bit (PCM8 only) APU: Added a sampling rate option in the .ini file MMU: Added support for the timer registers on the ARM7 side MMU: Corrected mirroring at 0x3800000-0x3FFFFFF on the ARM9 when WRAM is split GUI: Added a viewer for the ARM7 I/O registers GUI: Added support for .ds.gba files (the 512-byte loader is skipped so they are effectively treated as .nds files) GUI: Fixed problems with reading from the upper 32kB of ARM7 RAM in the disassembler 2006-03-15 *BLEEP BLEEP BLOP* APU: Added rudimentary sound emulation MMU: Added handling of sound registers GUI: Added a sound master enable option on the audio tab GUI: Fixed a bug where multiple instances of the same dialog window could be opened at once Only the PCM8 and PCM16 audio formats are handled right now. Sound mixing is currently fixed at 32kHz mono, so panning doesn't work. If it becomes too painful to listen to you can disable sound altogether through the gui or in the .ini file ;) 2006-03-14 CPU: Added a few missing LDM/STM instructions CPU: Added MRS/MSR SPSR CPU: SWI 3 emulation is more accurate MMU: Fixed some timer bugs MMU: Fixed some VRAM mapping bugs MMU: Fixed handling of out-of-bounds ROM accesses GUI: Fixed some bugs in the disassembler and memory viewer GUI: Added an auto update mode to the I/O register viewer GUI: DMA transfers can be logged to the debug console The CPU plugins is this release are not compatible with earlier versions of the MMU and GUI. 2006-03-11 GPU:...
