Mini vmac for iphone code#

In Mini vMac 3.2.3, the platform independent sound code also requests space in smaller chunks instead of a whole ticks worth of 370 bytes at a time. If it needs to write more than that, it is responsible for breaking up the write into two parts.

The platform independent code requests space, and is told how much contiguous space is actually available. In Mini vMac 3.2.3, this hack is not needed.

Since the ring buffer size is not a multiple of 370, this requires a hack, where the platform independent code actually writes past the end of the ring buffer, and the platform dependent code copies the excess to the beginning of the buffer. In Mini vMac 3.0.4, which Zydeco's iPhone port is based on, the platform independent code requests a 370 byte sound buffer every tick from the platform dependent code. The platform dependent code also adjusts how fast the emulation runs, adding or removing a tick every second, so as to keep the sound buffer filled to the desired amount, to keep latency as small as possible while avoiding buffer under run. The basic idea is a ring buffer that the platform independent code writes to, and the platform dependent code reads.

How-To guides, Documentation, Macintosh Software, and more. Then click on the close box of the Mini vMac window to quit theapplication. When you’re done looking at this, choose the “ShutDown” command from the “Special” menu on the emulatedscreen: The emulated computer should boot from thisimage, starting up the Finder, with a menu bar at the top of theemulated screen: The Mini vMac window should fill with a gray pattern, with a picture ofa floppy disk in the center, with a blinking question mark on it:ĭrag the icon of your bootable disk image, “System Startup”,onto the Mini vMac window. To get past this, drag the icon of your ROM imagefile, “vMac.ROM”, onto the Mini vMac window. Unless Mini vMac finds the ROM image file in one of the places it looks,it will display this message in the new window it opens: For most operating systems, you can double clickon the application’s icon. Use the ua608dcommand line toolto get the disk image “System Startup”from “SSW_6.0.8-1.4MB_”.(If you don't wish to use ua608d, see the Alternatives page.) Next, you will need a bootable disk image for the Macintosh Plus. (If you don’t have a Macintosh Plus, you could check the“ Where to buy an old Macintosh”page.)(And before you ask, the FAQ page has a section about ROM images.) Next you will need a ROMimage file from a Macintosh Plus.This file should be named “vMac.ROM”.A utility such as“ CopyRoms”can be used to obtain this file from your MacintoshPlus.
