		<summary type="html">&lt;p&gt;Initial version.&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Release Date ==&lt;br /&gt;
MAME 0.97u4 was released on 2 July 2005.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Contributors ==&lt;br /&gt;
The known contributors for this version are, in alphabetical order:&lt;br /&gt;
&lt;br /&gt;
* [[Aaron Giles]]&lt;br /&gt;
* [[Brian Troha]]&lt;br /&gt;
* [[Corrado Tomaselli]]&lt;br /&gt;
* [[David Haywood]]&lt;br /&gt;
* [[Highwayman]]&lt;br /&gt;

* [[ShimaPong]]&lt;br /&gt;
* [[smf]]&lt;br /&gt;
* [[Ville Linde]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Specific Contributions ==&lt;br /&gt;
The known contributions for this version are, in the order specified in the whatsnew:&lt;br /&gt;
&lt;br /&gt;
* [[Aaron Giles]] fixed the v60 SBR handling to ignore the low 12 bits. This allows the hack in tp2m32 to be removed.&lt;br /&gt;
&lt;br /&gt;
* [[Mamesick]] adjusted the volume balance in ddragon3, ctribe, mugsmash.&lt;br /&gt;
&lt;br /&gt;
* [[Brian Troha]] added correct sound ROMs to World Class Bowling Tournament and Deluxe.&lt;br /&gt;
&lt;br /&gt;
* [[David Haywood]] replaced the old Outrun bootleg with a new dump that passes the ROM test and has proper ROM names.&lt;br /&gt;
&lt;br /&gt;
* [[Nathan Woods]] made more PowerPC improvements:&lt;br /&gt;
** Fixed exception handling; previously the MSR register was stored in EDX, and EDX is not preserved across the call to ppc_set_msr()&lt;br /&gt;
** Implemented recompile_fcmpo()&lt;br /&gt;
** Fixed certain rules in rules.mak (some said drc_ops.h instead of drc_ops.c)&lt;br /&gt;
** Commented the MSR_* values&lt;br /&gt;
** Moved BAT registers into their own structure&lt;br /&gt;
** Added DSI and ISI exceptions (non-DRC core only for now)&lt;br /&gt;
** Moved READ*/WRITE* functions into ppc_mem.c&lt;br /&gt;
** Changed memory handling so that reading and writing are done through function pointers that can be changed at runtime (which would be useful if, say a MMU was implemented in the future :-))&lt;br /&gt;
&lt;br /&gt;
* [[smf]] made PSX/Namco System 12 improvements:&lt;br /&gt;
** Added Tenkomori Shooting&lt;br /&gt;
** Updated board notes from Guru.&lt;br /&gt;
** Removed rom patches from the namco system 12 driver&lt;br /&gt;
** Renamed sound program roms.&lt;br /&gt;
** Added support for dma&amp;#039;ing incomplete blocks from MDEC&lt;br /&gt;
** Added sprites x &amp;amp; y flipping&lt;br /&gt;
** Caches the decoded tpage fields.&lt;br /&gt;
** mask setting &amp;amp; dma setup updates status fields correctly.&lt;br /&gt;
** reverse flag only has an effect on original GPU&amp;#039;s.&lt;br /&gt;
&lt;br /&gt;
* [[Ville Linde]] made yet another fix to the PowerPC counters, reimplementing them from scratch.&lt;br /&gt;
&lt;br /&gt;
* [[Ville Linde]] improved the Model 2 driver:&lt;br /&gt;
** Added the second SHARC&lt;br /&gt;
** Fixed all the problems caused by the previous update&lt;br /&gt;
&lt;br /&gt;
* [[Pierpaolo Prazzoli]] fixed incorrect test in sauro.c video system.&lt;br /&gt;
&lt;br /&gt;
* [[David Haywood]] improved the Lethal Enforces sprites, allowing 2 sprite chips to be created.&lt;br /&gt;
&lt;br /&gt;
* [[Aaron Giles]] rewrote the System 32 mixer to support accurate implementation of the alpha blending modes. Sprite shadows and several other effects are still not yet implemented. And it&amp;#039;s much slower than before.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
