<p class=MsoPlainText>Geiger<EFBFBD>s Snes9x Debugger Mark 10</p>
<p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;
font-family:"Courier New"'>Coded by: Michael Springer (t.geiger@gmail.com)</span></p>
<p class=MsoPlainText>&nbsp;</p>
<p class=MsoPlainText>This version of Snes9x was compiled by Michael Springer
(aka Geiger).&nbsp; The official Snes9x team will not support it.</p>
<p class=MsoPlainText>GSD does not support either Glide, Fmod, or JMA. </p>
<p class=MsoPlainText>&nbsp;</p>
<p class=MsoPlainText>GSD was built with Visual Studio 2005 and the latest Microsoft
development kits.&nbsp; As such, you may need:</p>
<p class=MsoPlainText>&nbsp;</p>
<p class=MsoPlainText><strong><a href="http://geigercount.net/crypt/vcredist_x86.exe">Microsoft
Visual C++ 2005 SP1+ Redistributable Package (x86)</a></strong></p>
<p class=MsoPlainText><strong><a href="http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=2da43d38-db71-4c1b-bc6a-9b6652cd92a3">DirectX

<p class=MsoPlainText>&nbsp;</p>
<p class=MsoPlainText><b><i>Due to the way some things work, and to save myself
a ton of support headaches, this application will convert your ROM to be both
headerless and non-interleaved if necessary.&nbsp; It will also use this format
for saving.</i></b></p>
<p class=MsoPlainText>&nbsp;</p>
<p class=MsoPlainText>&nbsp;</p>
<p class=MsoPlainText>Features:</p>
<p class=MsoPlainText>&nbsp;</p>

subroutines (they are still executed)</p>
<p class=MsoPlainText>- Step Out . executes until current subroutine returns</p>
<p class=MsoPlainText>- Skip Op . goes to next instruction without executing
the current operation (be careful with jumps and branches)</p>

<p class=MsoPlainText>- All log, usage, and dump files are saved to the Log
subdirectory (user configurable)</p>
<p class=MsoPlainText>- Hotkeys for Run, NextOp, StepInto, StepOver, StepOut,
and SkipOp</p>

<p class=MsoPlainText>- SA1 breaks up code blocks and obeys Squelch.</p>
<p class=MsoPlainText>- SRAM viewable in Hex Editor</p>
<p class=MsoPlainText>- Register editing</p>
<p class=MsoPlainText><em><strong>Changed</strong></em></p>
<p class=MsoPlainText>- GSD has been integrated into the system changes the
1.51 base uses. This includes directory structures, config files, and other
changes.</p>
<p class=MsoPlainText>- SkipOp no longer reprints the previous line if its the
same one being skipped.</p>
<p class=MsoPlainText>- DMA trace now prints length in hex</p>
<p class=MsoPlainText>- Breakpoint addresses and the PC register will accept
up to eight characters and will filter out common address notation (&quot;$x:\/&quot;)</p>
<p class=MsoPlainText><em><strong>Fixed</strong></em></p>
<p class=MsoPlainText>- Merging usage files caused a crash due to incorrect
array sizes</p>
<p class=MsoPlainText>- Execution breakpoints work for alternate RAM addresses
(7E vs 00)</p>
<p class=MsoPlainText>- Usage maps were saved even if Auto Usage was off</p>
<p class=MsoPlainText>- Wrong bank for Opcode 4C (JMP)</p>
<p class=MsoPlainText>- Write breakpoints in PPU operations caused data errors
(which frequently caused code to take branches it otherwise wouldn't)</p>

<p class=MsoPlainText>&nbsp;</p>
<p class=MsoPlainText>Mark 9 Release 8 (1.43 code base)</p>
<p class=MsoPlainText>Released: 2005-04-19</p>

- Breakpoints no longer reset when resetting emulation<br>
- Proper read / write breaking and usage map marking for MV and other dual mode
commands<br>
- Trace flag now resets when resetting emulation. &nbsp;Keeps certain visual
problems from occurring when tracing is not enabled (Zelda: LttP). &nbsp;Visual
issues will still be present when tracing is enabled though, due to the way the
Snes9x code handles the trace flag.</p>
<p class=MsoPlainText>&nbsp;</p>
