<p>Created page with &quot;{{FormatInfo |formattype=electronic |subcat=Graphics |extensions={{ext|com}} |released=1986 }} &#039;&#039;&#039;FMAC2COM&#039;&#039;&#039; is a DOS utility that converts a <a href="/wiki/MacPaint" title="MacPaint">MacPaint</a> image file to a [[D...&quot;</p> <p><b>New page</b></p><div>{{FormatInfo<br /> |formattype=electronic<br /> |subcat=Graphics<br /> |extensions={{ext|com}}<br /> |released=1986<br /> }}<br /> '''FMAC2COM''' is a DOS utility that converts a [[MacPaint]] image file to a [[DOS executable (.com)|COM]] file that, when executed, displays the image in a bare-bones viewer. It was developed by Keith P. Graham.<br /> <br /> The COM file remains sort-of compatible with MacPaint format, though most software that supports MacPaint format will reject the files.<br /> <br /> == Format details ==<br /> FMAC2COM works by replacing the first 640 bytes of the MacPaint file with an image viewer. It assumes the MacPaint file starts with a [[MacBinary]] header.<br /> <br /> There was probably only one version of FMAC2COM, but there seem to be two widely-distributed variants of it, which differ by only a single bit. In the FMAC2COM.COM file, the byte at offset 411 is sometimes 0x10, and sometimes 0x18. It appears at offset 408 in the generated COM files. Best guess is the 0x18 variant is the original, just because the 0x10 variant is usually found without the documentation file.<br /> <br /> == Identification ==<br /> The first 640 bytes of the file are probably always the same, except for the bytes at offset 3 and 4, and the byte at offset 408 as noted above.<br /> <br /> For example, ASCII &quot;{{magic|$KPG PC-ROCKLAND BBS}}&quot; appears at offset 26.<br /> <br /> == See also ==<br /> * [[ICE (executable compression)#See also]], for other software by the same author<br /> <br /> == Software ==<br /> * {{CdTextfiles|simtel/simtel9510/disk1/DISC1/MAC/FMAC2COM.ZIP|FMAC2COM.ZIP}} - 0x18 variant<br /> * {{CdTextfiles|simtel/simtel9211/msdos/mac/fmac2com.arc|fmac2com.arc}} - 0x18 variant<br /> * {{CdTextfiles|nightowl/carrs/010B/FMAC2COM.ZIP|FMAC2COM.ZIP}} - 0x10 variant<br /> <br /> == Sample files ==<br /> * &lt;nowiki&gt;http://cd.textfiles.com/bthevhell/200/150/girl25.pic&lt;/nowiki&gt; (NSFW!)<br /> <br /> [[Category:Executable envelopes]]</div>
