GBA/NDS emulator

21 August 2007 - version 2.4d

 

No$gba v2.4d lots of new info on wifi and ds-lite

(*) no$gba/wifi can send/receive packets, commercial programs are still getting stuck somewhere in transmission. NEW in v2.4d: Pictochat is now successfully exchanging authentication and associations requests and responses. After that, on real hardware, the host should immediately send data frames (via port 090h presumably), in no$gba, the host doesn't send any such data frames for whatever reason (only the client does, via port 094h). Info on fixing that problem would be highly welcome. Built-in help text (in debug ver) contains almost complete wifi specs now.

- dslite/help: added the new backlight level bits in firmware user settings

- dslite/help: added caution on DS-lite destroying wifi ports 064h and 076h

- wifi/emu: emulates initial wifi-port settings and random register (mod 5FDh)

- wifi/emu: emulates primary wifi irq flag stuck zero while secondary nonzero

- wifi/emu: emulates corrected ports (004h,0ACh,0AEh,0B0h,0B4h)

- wifi/emu: emulates new ports (210h, 05Ch/06Ch, 062h/064h) and new mirrors

- wifi/help: added rx/tx signal/timing charts (rfu pins, aka 19Ch bits)

- wifi/help: added specs/cautions on primary wifi irq flag (2000214h.Bit24)

- wifi/help: added new mirrors (on read from 0ACh,0AEh,20Ch,21Ch,298h,2A8h,2B0h)

- wifi/help: added notes/info on ports 038h,19Ch,214h,21Ch and on W_CONFIG_140h

- wifi/help: fixed tx_hdr: rate 8bit (not 16bit) defaults to 1Mbit/s if invalid

- wifi/help: added new bits: port004h.bit0 tx_master, 008h.bit15 beacon_irq1

- wifi/help: major updates in timers chapter (reloads, IRQ13/14/15, 22MHz, etc)

- nds/help: pinouts for nds LCD sockets, wifi RFU boards, and powerman chips

- gui: mousewheel support (win98 or dos/ctmouse) (thanks jasper/idea, tilo/hw)

Front End

August 21st, 2007

Beta u23 Release

 

- Updated "RESOURCE.ML" file with more information, mostly adding MESS specific support. As a side, running MESS now should show you a fully accurate representation of what you have based on your romsets. Also, added some MESS specific command support.

 

- Changed order of checking for joystick movement to check UP/DOWN movements BEFORE LEFT/RIGHT. Hopefully those who were having any issues with scrolling the gamelist with a controller will have a better time with it.

 

- Fixed clone detection for Parent Set lookups when using COMPLETE DATA CHECK (F3).

 

- Added SYSINFO.DAT as a viewable DAT file. This is the default information file when using MESS. If you do not use MESS but still want the file, the latest one is always available at: http://mess.toseciso.org/_media/sysinfo.zip

 

- Added some regulation to F3 to only show DAT files available for that emulator. For instance, MESS will only attempt to show SYSINFO and PINMAME will show only HISTORY.

 

- Added informational line on screen and in console when using any "-list" commands which port to a file.

 

- Added interm support for the new -SPEED command that was introduced in MAME 0.118u2.

Shash has written a pretty large post with an informal to-do list. He's also managed to fix Dead 'n' Furious.

... I wanted to fix Dead'n'furious, as it seemed to fail rendering 3D or stall while getting ingame. I really didn't knew, so I started to work, first to understand why it was failing. The first debugging sessions showed that it was in fact sending stuff to the 3D renderer, so it wasn't freezing, only not rendering onscreen.

Screenshots and full text here:

My emulator emulates the fairly unkown COMX-35 computer from the early 80s and also some other 1802 based machines like the Cosmac Elf, Studio II and Cidelsa.

 

Current version is 0.8.3 and I'm still working on improvements, mainly on additional HW support for the COMX like disk support, printer and other.
