Yet Another Apple Emulator - Patches
There are tons of great free and shareware emulators for my MacOS X Laptop, but I want to use my beefy Linux workstation... I can SURELY get better than twice the speed of an original 6502!
I found YAE — Yet Another Apple Emulator, but I had to patch the source a little to make it compile on a modern gcc. I'll package them better soon (and mail the maintainer), but for now my POST ./configure patches are below.
Also of note, the speed limiter (to the authentic 1.04MHz) is implemented in speed.c if you want to increase the speed or disable it. Since I just want to edit and assemble, the timing shouldn't matter for me and I now have a WAY fast emulated Apple //e ;)

How to run YAE?
I applied your patches and got YAE to compile. How do you run YAE? I downloaded APPLET2E.ROM and DISK.ROM and tried ./apple2 -e ShadowKeep1.nib but I just get a window that says "Apple //e". The loop in main.c run running, but nothing happens. Do I need other files? thanks for any help, -m

It's been a while
and I don't quite remember! I'm using OSXII now, and the Apple hardware card in my Mac Colour Classic :) I'll see if I can dig it up for you...

Nevermind...
It seems I was trying to run //gs only disks. For anyone else who happens to stumble upon this page, two things I had to do to make YAE work for me: 1) cutting-and-pasting the above patch for Makefile didn't work for me. The line: +X_EXTRA_LIBS= -lX11 -lXext wasn't added... 2) Pressing F1 to swap disks would always cause a seg-fault after I entered the name of the new disk. I had to comment out the following lines in x_window.c: /* ctkwan: free previosly allocated string */ /* if( disk_name[6][0]!=NULL) free( disk_name[6][0] ); */ thanks for the tips, -m
