- -"Joystick on Port 1/2" specifies on which ports you have real -joysticks connected (as opposed to the joystick -emulation on the numerical keypad). Joysticks are only supported under -BeOS, Linux, RiscOS and AmigaOS (only one joystick). The port numbers relate -to the host machine ports. On the BeBox, port 1 is the upper one and port 2 -the lower one. You should only turn on the ports to which you have actually -joysticks connected, or the keyboard will behave erratically. Frodo has an -automatic joystick calibration. If you plug in a new joystick or change the -joystick settings, you should first move the joystick once in each direction.
+Under Unix, the settings window appears directly after starting Frodo, or by +pressing F10. Under BeOS, the settings window can be brought up by selecting +the "Settings..." menu item in the running emulation.

+ +Frodo offers three different modes for drive emulation (see here for details):
+ +
+ +The button labeled "Browse..." opens a file selection dialog for a +more comfortable selection of directories and .d64/x64/.t64/LYNX files.
+ +If "Enable Full 1541 Emulation" is turned on, the four emulated 1541s +are disabled and replaced by a single 1541 emulation (drive 8) that only +operates on .d64/x64 files, but emulates the entire 1541 hardware and is +compatible with most fast loaders and some forms of copy protection. +However, it has considerably slower disk access and can also slow down the +emulation. If you have a .d64 with a program that doesn't load with the +normal emulation (see above), you may have better luck with the full 1541 +processor emulation instead.
+ +With "Map '/' <-> '\' in file names" you control whether the +'/' in C64 filenames will be translated to '\' and vice versa for Directory +Mode drives. The '/' character is used to access subdirectories under +Unix/BeOS, but as the C64 doesn't have subdirectories, it's a valid part of +a C64 file name. This is a problem if a program wants to create a file with +'/' in it as the host system would interpret the part before the '/' as a +directory name and, finding no such directory, would return an error and +the operation would fail. If you activate this checkbox all '/'s will +transparently be translated into '\', so in directory listings the '/' will +still appear. If you turn off this option, you can of course use the '/' to +access files in subdirectories from the C64.
+ +
+ +"Doublescan Lines" is only available under BeOS for the "Screen" +display type. It removes the black lines between scanlines, but makes +the emulation a bit slower.
+ +With "Display Sprites", you can switch the display of sprites on and +off.
+ +"Detect Sprite Collisions" determines whether collisions between +sprites and between sprites and graphics should be detected. Turning off +collisions will make you invincible in some games (sadly, your enemies are +likely to become invincible, too :-/).
+ +The "Sound Emulation" selection controls the type of sound output. +"None" means no sound (faster), "Software" turns on the +software 6581 SID emulation. Under Linux, there is another option, +"Catweasel" for using a hardware SID chip on a Catweasel board (you +also need Catweasel kernel drivers for this).
+ +The "Enable SID Filters" field enables the software emulation of the +SID sound filters. Some C64 music may sound better with the filters +disabled.
