The preview-alpha version of SNEmulDS 0.6 is now available for all the brave testers around the world!

The GUI artworks are not ready, so you have a "naked" and not very pretty GUI, but at least, you have the multi languages support!

You can check if your language is correct.
You can choose one of the language in the firmware or some language by editing the snemul.cfg :
# Language of GUI
# -1 -> Use firmware settings
Firmware languages:
# 0 -> Japanese (Katakana only)
# 1 -> English
# 2 -> French
# 3 -> German
# 4 -> Italian
# 5 -> Spanish
Non firmware languages:
# 106 -> Portuguese
# 107 -> Catalan
# 108 -> Polish
# 109 -> Dutch
# 110 -> Danish

Various External RAM packages can be used to improve large rom emulation, see snemul.cfg for more informations.

Scaling support has three modes :
- Full screen : nearly like snezzids
- Half scaling : "smart" scaling, only reduce half the backgrounds, and doesn't squish sprites. It looks quite fine in games.
- No scaling : no scaling at all, classic SNEmulDS mode, still default


Here is the complete list of changes compated to 0.5 beta:

- New GUI using framebuffer for sub screen
- Better human interface, improved file selector (alphabetical sorted), buttons, check boxes, multi choose zones, etc.
- New GUI supports joypad (joypad is not supported when emulator is running however).
- Multi language support (more than 10 supported, including katakan japanese !)
- Memory pak support (Opera RAM, Slot 2 card reader, etc. using libram) with paging or with large ROM mapping
- Scaling with pseudo bi-linear filtering and sprites squishing : full screen scaling (like snezzids), half scaling (half scaled and without sprites squishing), and no scaling (classic snemulds mode)
- Autiomatic SRAM saving when needed
- Some other bugfixes and improvements in GUI

Here it comes. Not as many fixes as I expected to put in this release, but did not want to delay it any longer. There is no change to sound core so don’t expect any improvement there.

Remember what I said about no hardware bilinear upscaling in NDS in the last note? Actually I was wrong - you can get it with some simple tricks. So now you can toggle between no scaling / nearest neighbour / bilinear with Y button.

Lameboy DS 0.9

Changelog:

* fixed: joypad register emulation (fixes Wario Blast)
* fixed: GBC hdma (fixes Pokemon Crystal graphics)
* fixed: interrupt flags emulation (fixes Bouble Bobble)
* fixed: V-blank interrupt timing (fixes Altered Space)
* fixed: split window emulation (fixes Donkey Kong graphics)
* fixed: GB timer initialization (fixes Pokemon Pinball)
* added: fake serial interrupts (fixes many early games)
* added: RTC emulation
* added: pseudo bilinear upscaling mode

RTC feature needs more explanation. I tested it with only one game - Pokemon Crystal, so it can be considered beta. The emulated time is always synchronized to NDS RTC and not affected by fast mode. It’s the same behaviour as in VBA and opposite to GNUBoy’s. Also save style is compatible to VBA, with one issue: I think there is no way to check time zone in NDS (as it is not set) so I fixed it to +2h. If your timezone is different you will get timeshift between Lameboy and VBA.

I'll release an extremely early build just to get feedback.
Yes, this is extremely early. Does not support sending programs to emulator, or savestates. Only emulates a TI83.

How to use:
* First append a TI83 rom image to the end of the .gba file, using something like copy /b ti83emu.gba + ti83.rom ti83emu_rom.gba
Keys:
SELECT: Toggle keyboard overlay
Keys (keyboard visible)
* Arrows: Move cursor
* (right now cursor is not displayed over arrow keys, just move it away a few times)
* A: Press that key
* B: Quick Keys
* Start: ENTER
* L: Alpha
* R: 2nd
Quick Keys: (Hold down B while keyboard visible)
* A: ENTER
* Arrow Keys: Arrow Keys
* (other keys same as keyboard visible)
Fullscreen Keys:
* Arrows: Arrows
* A: 2nd
* B: Alpha

New version...
Has a Link Feature.
Append the TI83 ROM, then append a single .83g file.
Press L+R in fullscreen mode to send the attached 83g file. (uses silent linking, calc must be on and at homescreen)

Well, I've just released version 1.1 of savsender on my website. This version supports writing the EEPROM, in addition to the regular dumping functions. I've tested this with both MKDS, SM64, and Brain Age, and it seems to work properly.

In addition, I've fixed the config file parsing so it'll deal with whitespace at the start and end of config lines. This should make Mac users happy, as it will now handle any line-ending style, as well as extra spaces, etc.

Enjoy!

Not much has changed since the last version, just wanted to get it out if Dwedit wants to update his version. Mostly SG1000 stuff.

*Optimised tile rendering for mode 0 & 2.
*Fixed a bug where GG games set the "lock-toprow" bit (Sonic Drift demo).
*Added support for the SG1000 games Mahjong and Home Mahjong.
*Added support RAM on some SG1000 games (The Castle, Othello...).
*Fixed clearing of SMS VRAM when no bios used.

This version aims to improve in sound and graphics. As the emulation becomes more and more complex, it is more and more difficult to add new features without breaking the emulation overall, so some new feature will not be enabled by default for all games. The configuration file select which features are enabled or not, and becomes very important (so don’t forget to put it in the root directory!).

I tried very hard to improve sound, and i succeeded to get much better musics in some games, but there may still some “pops” or “cracks” sometimes, and the sound can slowdown or goes mad in some rare circumtances (the ARM7 seems not powerful enough).

A new menu has been added : the GFX config menu, this menu offer a simple way to change the GFX behaviour in real time. The emulation is not stopped like in the options menu, you can enable/disable several features and see which ones are better for the game. (See README for more informations)
Here is the list of changes

* Changed the Sound timers, now the timers should be a bit more accurate and removed the timers hacks
* Moved back the Sound RAM in the fast ARM7 RAM, removed unused code from ARM7 codes
* Now support sprite address change during frame (limited to two addresses by frame), this makes Ogre Battle much more playable
* Left handed people can now enjoy the SNES mouse option (right buttons can be used like left joypad).
* Options can now be saved in configuration file
* New SNES config menu
* Fixed some bugs

Optionnal feature (enabled by configuration file):

* Added sound synchronisation fixes, this is a set of flags that make ARM9 slowdown or make ARM9 wait for the ARM7. Those options make Square games (and other games) sound much better, but also break sound in other games. So this option is available through the configuration file. I only changed for the configuraiton file for Chrono Trigger, SOM1 and FFVI. You will have to modify the configuration and test the options for other games.
* Added priority per tile for BG3, by detecting if there are more low or high priority per tile at each line (see README)
* Added priority per tile for BG1 and BG2, by using the fourth DS layer. Low priority tiles go to fourth layer, and high priority per tiles (this idea was taken from SNESAdvance). This option is useful for SOM1 and FFVI (set it to BG2).
* Sprites priorities can now be changed. See configuraiton file for more informations. The default is 1123 but 1223 makes some games look better (like Castlevania IV first level for instance)

Hi all at DS Scene

About 5 years ago I have wrote partial gameboy emulator in C purely for fun, so it never gone public. To try some NDS programming I have just ported it NDS. As there is no DLDI emu realesed for NDS I decided to add support for it and release here. Rom selection menu is based on work done for StellaDS by spathi-wa from r4ds forums.

Some emulator (mis)features:
- no sound emulation
- no or incorrect serial/ir/dma/cpu emulation
- no realtime sync, game will go as fast as it can
- full speed for games that use less than about 50% of GB CPU
However some games are playable anyway.

How to use:
- copy rom files to /lameboy/ dir on your flash card
- run lameboy.nds and select rom
- in game keys:
-- L+R - back to rom select
-- Y - switch fullscreen upscaling on/off
-- X - save persistant ram to .sav file
