| NGPAdvance V0.2 | 4 September 2008 |
|---|
New version of NGPAdvance, a lot of games should be a bit more playable
thanks to speedhacks. I also added support for a lot of internal hardware
(RTC/Alarm, Power button, DA/DA IRQ) so that you can use the real bios.
Still no flash emulation as I can't really see how to implement it on the GBA...
Also uploaded a tech doc for the NGPC.
*Added speedhacks for a lot of games.
*Added emulation of batteries & sub battery.
*Added RTC alarm.
*Added power button (SELECT).
*Added D button (R) (check Doko Demo Mahjong).
*Fixed a couple of cpu bugs affecting Metal Slug 1 and a couple of other games.

New emulator! Woho! Well just like the Wonder Swan emulator this is really slow.
It doesn't support any kind of saving so some games won't work correctly or at all.
Other games have graphical glitches and are really slow.
Some games doesn't work and it's really slow.
It is indeed slow but there are a few things you can do to speed it up a little bit.
You can turn off the Z80 for some games (experiment when to turn it on/off) and you
can lower the clock of the TLCS-900 cpu.
*First release most things implemented except flash/save..

I'm still alive and working my ass off coding an emulator for the DS.
I promise I will put up something new here very soon.
Oh and don't forget to visit WiiCade from your Wii
if you want some cool flashgames to play on it.

Christmas time! =) Wii! I'm still poking around with the web site and stuff,
got my own webspace and a domain name (ndsretro.com). It's mostly because I
wanna learn PHP and mess around with style sheets for the DS browser (Passagen
screwed that up), I've tried building a better stylesheet for the DS browser
but I still don't know if I'm gonna put in links to the other pages as well.
If things doesn't work as they used to, my passagen mail still works.

| Cologne V0.7 | 5 September 2006 |

*Fixed "Go Multiboot" when used from Pogo.
*More colorful palette.

Surprise! A WonderSwan Color emulator for the GBA, it's actually not that much
to cheer about as it's dead slow, but it works as far as playing Final Fantasy.
To speed it up I need to rewrite the cpu core and even that will probably just
make it slightly faster, so it looks like it's a dead end but I did give it a try.

I've kind of taken a vacation from the GBA for a few weeks but I've still got SMSAdvance V2.0 coming up
, just want to fix sample playing in the sound core if it's possible. If anyone of you out there got
any bugs to report, now is the time to do that.

save SRAM and savestates for every game. Hope you like it =).
