DSemu v0.0.3b released!

Friday, 8th April 2005

I've implemented the screen-flip bit in POWERCNT, so anything that uses that feature should work correctly now. In particular, the ARM Wrestler will appear in its right place, on the top screen. Also, regarding the opening of ROMs, I've attempted a hack at type selection; anything with an NDS extension will load in DS mode, and anything else will open as a GBA rom. I know it's buggy and it will break, but it should help a little.

 

In other news, Normmatt seems to have finished his configuration editor dialog. I haven't been able to grab his code and take a look just yet, but I shall do so for a release in the near future. That should help matters regarding the config file.

It's been a slow few days; there've been maybe a couple of bug fixes in the source, but not enough to warrant a new release. I am going to start tracking down the bugs in the CPU that seem to be stopping the majority of demos from running, though. It could be a long process.

 

I'm not sure that too many people were able to catch the hint in the last post, but the emulator does now have two CPU cores. The ARM7 doesn't actually do anything, and there's nothing else on the bus (a touchscreen controller, for example) for it to interface with, but it is there and executing. If only something actually ran, I could see it in action.

 

Regarding CVS, it has been out of date recently. Not to worry; I've updated all the existing files, and added in the new ARM9 and its associated files, so any checkouts from CVS should be current now.

Sega ST-V update [Angelo Salese]

* Fixed some interrupt issues because the old implementation was giving several hangs

  on the above game.To be more specific added the sprite draw end irq to the INTERRUPT_GEN

  structure & fixed a bug which prevented the vblank bit to not be cleared if the irq mask

  has the VBLANK-IN disactivated.

* Fixed the NMI_disable/enable cmds on the SMPC device,his function is to active/disactive

  a bit in the SMPC ram.This fixes the "2 credits bug at start-up" in Shanghai Triple Threat.

  Shanghai Triple Threat to not show correctly.
