Author:   bauec002@goofy.zdv.uni-mainz.de (Christian Bauer)
Type:     misc/emu
Replaces: misc/emu/Frodo.lha
Version:  2.1
Requires: AmigaOS 2.1, 68020

Frodo is a multitasking freeware C64 emulator for the Amiga.
OS2.1 and a 68020 (or better) are required, as well as copys of
the original C64 ROMs, which are not included.

This emulator focuses on the exact reproduction of special graphical
effects possible on the 64, and has therefore relatively high system
requirements. Using a 68060-50 and a CyberVision card gives about
140-160% of the original C64 speed in standard text mode in the
emulation's most precise mode and about 700% in its fastest mode.

Using a line-based VIC model, Frodo is capable of running most games
and demos correctly, even those with FLI, FLD, DYCP, open top/bottom
borders, multiplexed sprites etc. A single-cycle version of the
emulator, "Frodo SC", is included that runs even those programs that
fail on the line-based emulation.

A graphics card (any one whose modes are selectable with a screenmode
requester will do) is strongly recommended for faster display as the
emulator's routines have been designed for a chunky display memory.

Some small demo programs and the full source code in C and assembly
language are included in the archive.

Changes from V2.0:
 - The C64 character ROM is now included in the archive
 - Fixed write errors in 1541 "Dir" mode
 - 1 bit Amiga mode fixed
 - SID type gadget is localized
 - Reset6526 stops timer B counting underflows of timer A
 - Sprite display can be turned off
 - Corrected VIC interrupt handling, raster interrupts can be
   triggered by writing to $d01a
 - CIA interrupts cannot be cleared by writing to the ICR
 - Better CIA 1 PRA/PRB emulation (keyboard/joysticks)
 - Corrected SAM CIA timer output mode display
 - SAM can be invoked from the "Illegal Opcode" requester
 - 6510 registers can be modified from within SAM
 - The file name for the "o" command in SAM must now be surrounded
   with quotation marks (")
 - Added load and save commands to SAM
 - Frodo SC: SAM "vv" command works
 - Frodo SC: Implemented 3-cycle-delay when starting timers
 - Frodo SC: LPY register reported wrong values
 - Frodo SC: Implemented simple sprite display (no collisions, no
   priorities, sprites are drawn over the border)
 - Frodo SC: Corrected display of background color in left/right border
