Uploading to Jaguar with JUGS enabled BattleSphere
|
First of all make sure you have a BattleSphere by Scatologic,
no easy task I think, but maybe that will change once chip prices drop and
Scatologic can make many.
Next make sure that you have a fully working JUGS system. I am using an old
laptop running DOS and Windows to develop on, (but understand from the technical
requirements that this should be enough,) although I do not own JUGS. The
supplied DOS loader supports only .BIN files and a supplied utility converts
.ABS files to .BIN files. Badcoder will provide .BIN files for JUGS users
normally as they work on BJL and Alpine too. Warning - reports indicate they
load SLOWLY. |
 I do not know if there
are different versions of the DOS uploader, the JUGS software itself is
built-into the normal BattleSphere cartridge ROM.
This screen shows the system "unlocked". A secret cheat has to be entered
in BattleSphere to unlock JUGS (I cannot tell you it) and then some special
button combination activates it. The baud rate can be set. |
| Usage: JUGS.EXE [options]
-com=<COM1, or COM2> Port number for COM1 or COM2
-baud=9600, 19200, 38400 Serial Baud Rate
-file=<name string> Name of file to load
-addr=<load address> Address to load file to (Hexadecimal)
-run=<load address> Run flags (see below)
0 = Run immediately
1 = Reset DSP then run
2 = Reset GPU then run
3 = Reset DSP and GPU then run
|
 While the binary is loading
you do not see anything particularly special, unless the program occupies
the RAM where the video display is sitting. (I do not know which binaries
are affected, or at what address.) Apparently music plays during loading,
but as the uploader is serial rather than parallel like the BJL, JagServer
or Alpine, it is can take several minutes to upload the binary via JUGS.
Some Underground binaries are apparently not compatible with JUGS as they
do things which cause it to fail during loading. Scatologic has some fix
programs on their web-site to deal with these problems. |
