         AMIGA FREQUENTLY ASKED QUESTIONS.

I HAVE INSERTED A DISK AND IM GETTING THE ERROR "RETURN CODE 20" or "UNKNOWN COMMAND".
Return Code 20 means that he OS you are trying to the run disk on is not high enough. For example: If you are trying to run a A500+ disk with OS V2.0+ Workbench files on an A500 setup, then you will get such an error. An Unknown command error can be one of two things in emulation. The first one is that the file the disks is looking for to boot up is missing or that again, you have the incorrect operating system running.

WHEN I INSERT A DISK IT DOES NOTHING.
This means the disk is either not bootable and has to be loaded in Workbench or you have the incorrect OS. For example: The disk boot-up system has been designed for the A1200 and will therefore not boot on an A500.

HOW DO I SCREENSHOT IN WINUAE?
There are a couple of ways of taking screenshots in WinUAE. The first way if you have the newer version of WinUAE is to get to the point at which you want to take a screenshot. Press F12 then click on the "Output" tab and then "Save Screenshot". This will save a BMP image in the folder "ScreenShots" located in your WinUAE folder. The alternative way is to first open up your paint program and then open WinUAE. Get to the point you want to take a screenshot and press Print Screen on your keyboard. Once you have done this, press ALT+TAB so you can "select" your paint program and then go to Edit and then Paste.

WHATS THE DIFFERENCE BETWEEN AGA AND ECS?
AGA and ECS are the chips used to determine graphics. The ECS chipset is generally found in the older A500/A500+/A600 Series of the Amiga machine and the AGA chip is generally found in the A1200/A4000 machine. Obviously AGA is the better of the two as it can handle more colours on screen at one time. AGA software will not work on an ECS machine.

WHAT IS AN ADF FILE?
An ADF file is an Amiga Disk File image, basically its a whole disk put together into one file. ADF files can be created on an Amiga by using a program called Transdis. The file can then be sent to a PC via a serial cable using a terminal emulation program.

WHAT IS A KICKSTART ROM?
A Kickstart ROM is the brains of the amiga. To use an emulator you need the Kickstart converted into a file. Kickstart roms are still under strict copyright protection so Im afraid I can't supply you with any. If you have an Amiga, you can use a program called Transrom. Alternatively, you can purchase the Amiga Forever CD-ROM from http://www.amigaforever.com which contains Kickstart ROMS.

WHATS THE BEST EMULATOR?
All of them have there good and bad sides. Fellow seems to be slightly faster than WinUAE but WinUAE seems to be more compatible. So I would say it's a good idea to have a copy of both emulators because if something doesn't work in one, it may work in the other.

CAN I CONVERT DMS TO ADF?
Yes you can using a program called XDMS. The program is very simple to use, this is how you would convert a DMS file to an ADF file:

xdms u disk.dms

The above command will unpack disk.dms to disk.adf in the current directory.
