long ago. I dont even know where the cables are or if i can still make them. I only have a serial cable, so it takes hours and hours.

This isnt pointed directly at you SSaxdude, but please do not ask me how to make backups. That discussion has been against DCemu site policy since the very beginning, and will remain so.

Does anybody know how to use a gamepad with this. I tried using a Xbox controller and a Microsoft Sidwinder but neither worked. I also tried messing with the plugins but that didn't work either. Its kind of hard playing Dreamcast games with a keyboard.

First game I tried is Sonic Adventure (PAL). Seems to be playable.
When you need to select the memory card, you can't see anything. It also happens in the Options and when you select a character. On these screens, after 20 seconds, the music dies.
You cant' see the text when the characters are talking and sometimes the music dies for 2 or 3 seconds. No graphic problems ingame. Excellent speed, totally playable.

@ SSaxdude: If you need help dumping games, contact me

@ BrooksyX: there isn't good support for gamepads on this release, sadly try using your keyboard.

Yeah, I guess we will just have to hope it will be added in the next release.

'Undocumented' nullDC features

nullDC.cfg file :
There are varius settings that are not exposed in the interface.That includes AntiAlias & resolution settings for the pvr plugins.To restore default settings , just delete the config file .

Command line params (These are mostly usefull to developers):

-nosse2 , -nosse3 , -nossse3
These disable the use of some instruction sets (sse2/3/S3).(Not realy usefull)

-serial "file here"
Redirects the serial output to the given file.It can also redirect it to a COM port (-serial \\.\COM1).The file MUST exist before loading nullDC.

-slave
Writes serial output to pipe1 , reads from pipe2.The handles have to be created properly first (ie : -slave 912 913).It can be used to redirect the serial IO to another application

.gdi files:

The ImageReader plugin supports a format to load gdrom dumps.
here's the structure :
Entry Count
Track StartSector ctrl SectorSize File Offset
....
Track : track number
StartSector : start sector on the gdrom to map the file
ctrl : 4 -> data , 0 -> audio
SectorSize :Sector size for the data in the file , 2048 , 2352 & a few others are supported.If this is set to 0 the file is considered 'missing'
File : file to read the data from
Offset : byte offset into file to read the data from. Can be both negative and positive

The first 2 entrys are for the low density area (tracks 1 & 2,session 1)
The rest of em are on the hi density area (tracks 3+ , session 2)

Here are a few examples :

Tony Hawks Pro Skater 1:

Code:

5
1 0 0 0 none 0
2 0 0 0 none 0 3 45000 4 2352 45000to63139.bin -8
4 63288 0 0 none 0 5 69313 4 2352 69313to549150.bin -8

the 1,2 and 4 tracks are missing from my dump , the -8 is to offset the files a bit (dumped using cdrwin so the format is a bit different)

Visual Park

Code:

13
1 0 0 0 none 0
2 0 0 0 none 0 3 45000 4 2048 track3.iso 0
4 445516 0 0 track04.raw 0
5 449104 0 0 track05.raw 0
6 453213 0 0 track06.raw 0
7 455855 0 0 track07.raw 0
8 469617 0 0 track08.raw 0
9 483437 0 0 track09.raw 0
10 486080 0 0 track10.raw 0
11 491965 0 0 track11.raw 0
12 543479 0 0 track12.raw 0
13 547889 4 2048 track13.iso 0

tracks 1,2,4,5,6,7,8,9,10,11,12 are missing here (audio tracks -- they just get replaced by silence)

Thats it , i hope that helps.
