Mini vMac 37 *Alpha*

Variations Service (Basic) Directions

Alpha! Variations for the current stable version are available from the main Mini vMac Variations Service page. For more information about the Alpha, see the Mini vMac 37 download page.

Mini vMac has no preference settings, which helps to keep it small, simple, and reliable. Instead, options can be chosen at compile time. You can compile a variation of Mini vMac with options you desire following the instructions on the Build page.

Or, I can compile variations for you.

With a donation to the Gryphel Project of ten dollars or more, you will receive a “Sponsor Code” that can be used to request custom variations, as many as you could reasonably want for a period of a year. You can make as many copies of these variations as you want, and give them to anyone, under the GNU General Public License (GPL).

Without a Sponsor Code, you can request Demo versions, that are identical to the regular version, except that the word “Demo” floats around the emulated screen.

Select the options you desire from the Mini vMac *Alpha* Variations Service (Basic) page, including your Sponsor Code if you have one, then press the “Make custom variation” button at top. (The link in each option’s name leads to documentation for that option.)

In around 5 seconds, a page will appear with a download link. Click on the link to download your compiled variation. (You should probably also save the page, to record the options chosen and other details.) You can also verify md5 checksum and message signature displayed on the page.

Meanwhile, the Variation Server has been double checking, by compiling the variation a second time. If you reload the page with your web browser (another 5 seconds or so after the page first appears), a line at the bottom that said “Preliminary Result” should change to “Final Result (both compiles match)”. Otherwise, an error will be displayed.

To prevent taking too much space on my hosting provider’s computers, older custom variations will eventually be removed. So please download your variation promptly.

After you download the variation, extract the application from the archive, and place the appropriate ROM image file into the same folder, just as is done for the standard compile of Mini vMac. Mini vMac does not create preference files or change registry settings or make any other changes to your computer. So there is no problem in having multiple variations of Mini vMac installed.

The Basic Variations Service offers only a few options. Many more options can be accessed through the Advanced Variations Service. For updating an existing variation, either to change some options or to use the same options in a newer version of Mini vMac, there is also the Text Based Variations Service.

Some fine print

The Variations Service only promises to build variations accurately from the public Mini vMac source. No guarantee is made that the built variations are suitable for any purpose. (Please report any bugs.) It is possible that some variations can not be built at all due to bugs in the Mini vMac source. Otherwise, requested variations will be built eventually, but there is no guarantee of how long it will take, due to hardware failures and such issues.

The Variations Service is reproducible. That is, if you ask for the same options twice, you will get the exact same application archive. (The file name will be different, but the contents are the same.) The Sponsor Code used does not effect the resulting Variation, so two sponsors requesting the same variation will get the same result. (With no Sponsor Code, a demo is created, which is different from the sponsored variation.)
