The chipset configuration will determine features of the graphics and sound facilities provided on the emulated amiga.
Chipset - There are three releases of chipsets for the Amiga:
OCS - Original Chipset. Contains Agnus (512K), Paula, Gary and Denise
which provides 32 colours (4096 in HAM mode),
with 4 channel stereo sound using upto 512K of Chip RAM.
ECS Agnus- Enhanced Chipset with just the new 1MB version of Agnus chip.
Full ECS - Enhanced Chipset with a 1Mb Agnus chip and the new Denise
chip which supports new graphics modes such as
Productivity Mode.
AGA - Advance Graphics Architecture. Has a completely new chipset called
Alice (replaces Agnus) that supports 2MB of Chip
RAM, Lisa, Gayle and Paula. This chipset supports 256 colours (256K in new HAM
mode), bigger sprites and more resolutions
than the older chipsets.
PAL or NTSC - Select type of TV resolution you require.
Draw 1 frame in x - Select number of frames to draw. Adjusting this can slow down or speed up display.
Sprite collisions - Modes are Sprites & playfields, None, Sprites only and Full.
Sprites are hardware based objects which the chipset
can directly control. For example, the mouse pointer is a sprite.
The other types of objects are called BOBs (Blitter Objects which are graphics,
cut and pasted onto the screen and are slower than sprites).
A playfield is the background objects such as landscapes which sprites may crash
into.
Immediate blits - Enable immediate blitter updates on the display.
Keyboard shortcuts
F12 + S - Toggle between windowed display and full-screen mode (if suppported
by the graphics driver).
F12 + G - Toggle mouse-grab mode (in windowed mode)
F12 + M - Toggle mousehack mode (if mousehack is running)
F12 + I - (or Scroll Lock) Toggle display inhibit (Amiga screenmodes,
not P96)
F12 + P - (or Print Screen) Save screenshot (if supported)
