SDDapple - rewrite of Dapple for SDL

* Emulates Apple II+ with 64K RAM, or //e with 128K RAM.


* All II+ graphics modes are emulated (minimal testing on Screen 2 though)

but hi-res graphics emulation is imperfect.

* END key exits. Ctrl-F12? resets. F1 and F2 change disks. F11 switch

between windowed and full screen modes.

* Disks are expected to be disk6a.dsk and disk6b.dsk at startup.


* Larger PO-type disk images can be provided in Slot 5 as hdv1.hdv and

hdv2.hdv; these are the same format as in ApplePC and most other
emulators. The source code defaults these images to 800K when formatted
under ProDOS.

* A single PG2 file can be named quikload.pg2, and loaded by pressing

Alt-F11?. The A value is what to CALL. (if it says A02045, you need to
type CALL 2045) Also, you can load PG2 files with Alt-F6? (as in very
old versions of Dapple).

* The header information can be displayed (in hex only) by typing the command: sddapple -h


* Full BWOR mode has been added to SDDapple 0.1; hybrid BWOR mode is

available and you still get regular mode as default.

* To use hybrid BWOR mode (REE on top of existing monitor): sddapple -H


* To use full BWOR mode (don't load monitor.rom at all): sddapple -F


* To use Apple //e mode (see below for caveats): sddapple -E

You need to use uppercase E, F and H.

* No disks work correctly in full BWOR mode. You'll need to use a

compatibility mode or PG2 loader to load programs.

* The cursor doesn't show up in hybrid mode.


* Be prepared for unusual behavior when using BWOR REE modes. BWOR's

emulation of the ROM code is incomplete but runs at the native speed
of the host computer.

* The BWOR REE replaces the 6502 disassembler from the native ROM with

a 65C02 disassembler. You will notice a difference in the format of
disassemblies.

* The monitor and BASIC ROMs have been split. A regular 12K (FPBASIC from

the August 1980 System Master will do just fine) Apple ][+ is usable in
normal mode, but in Hybrid mode, you need to run BWROMMAK to separate
the BASIC and the monitor into two separate files. In full REE mode you
only need the BASIC ROM; if you don't have a 10K BASIC you will need to
run BWROMMAK.

* Preliminary Apple //e support is available; you need a 16128-byte ROM

from a //e. This corresponds to bytes $C100 and up. Slot 3 isn't
implemented, nor any of the new video modes, and the MMU and IOU are
incompletely emulated.

* F3 and F4 alter the CPU multiplier, which affects the CPU speed. A

multiplier of 1 should run at about 1 MHz. This works by changing how
many cycles, in increments of 65, are let rest between the redraw of
two scanlines.

* Alt keys ONLY function in //e mode. In that mode they do the expected.


* The original //e ROM is detected by checksum (16-bit adder, same used to

detect BASIC versions when the REE is enabled). If found, MouseText? is
disabled. If not found, MouseText? will be available.

* CPU multiplier is set for a Frameskip of 5 by default

This is inaccurate, but for some reason runs closer to the original
speed (note the slowdown caused by the new video code), and the sound is
fairly accurate. The code is taken from KEGS via an Alpha version of
EMUII. KEGS is copyright 2002 Kent $#@!ey and licensed under the GNU General Public License (as SDDapple is also).

Good Job, yall.
just a quick question, will there be a virtual keyboard, like th emulated ST, Amiga, and atari 800 had?

[ron]

If you think that the emulator can be a candidate to be released seriously , why not ?.

We're working on a common GUI. Soon more news.

[obelisk]

thank you ron, you guys are the best.

[quzar]

how does this compare to Apple II Soul Captor? (in terms of compatability and speed, i already know it is newer)

[ron]

For playing games and basic apps is enough compatible, obviously all software will not work but I think same than soulcaptor, with sound.

[turnerl]

thankyou thankyou thankyou Ron you are the BEST!!!!!
