.TH "MAKEATR" 1 "2024-05-10" "0.9.0" "Ken Siders' Atari 8-bit Tools"
.SH NAME
makeatr \- convert an Atari executable to a "K-file" bootable disk
.SH SYNOPSIS
.sp
makeatr \fIimagefile.atr\fP \fIatari\-executable\fP
.SH DESCRIPTION
.sp
For various reasons, it\(aqs sometimes useful to make a bootable disk
image of an Atari executable. \fBmakeatr\fP does exactly that.
.sp
If you have a bootable image made with \fBmakeatr\fP, but you\(aqve lost
the original executable, you can extract it from the image with
\fBunmakatr\fP(1).
.SH NOTES
.sp
\fBmakeatr\fP is only useful for single\-file games or other programs
that don\(aqt need DOS disk access to run: the bootable image
won\(aqt contain any DOS at all, or even a DOS file  structure
(you can\(aqt read the directory).
.sp
Disks made with \fBmakeatr\fP are recognizable when booted on the Atari,
because they display a GRAPHICS 0 screen with a lowercase k (screen
is otherwise blank).
.sp
Disk images made with \fBmakeatr\fP are only created with enough sectors
to hold the executable. AtariSIO can handle these images fine, as can
most other ATR utilities, but the smaller\-than\-regulation size may
cause problems with some utilities.
.sp
There is only one Atari executable format, regardless of filename
extension. All .XEX, .COM, .BIN, .EXE, etc. files for the Atari are
the same file type, regardless of the name, and regardless of what
you may have read on some forum site. Atari DOS doesn\(aqt care about
the filename; it only exists for human consumption (and for filetype
association with emulators, these days).
.SH DIAGNOSTICS
