Auto ModellistaAuto Modellista shows a nominal 60 fps counter but is not consistently smooth in the Lite ARMSX2 test. The reviewer reports slowdown and about 50 fps near the finish; the initial setup is 1×.Pocket Duo Lite
Shrek 2Shrek 2 is close to full speed but choppy on Lite. The reviewer tries EE cycle skip and cycle-rate changes, then says the result may be worse. No reliable underclock fix was found.Pocket Duo Lite
Twisted Metal: BlackTwisted Metal: Black varies sharply in the Lite ARMSX2 test: the reviewer describes roughly half speed in busy scenes and full speed in emptier areas. They repeat 1× resolution and disabled hardware downloads. Shrek 2’s earlier EE cycle changes may still have applied.Pocket Duo Lite
Need for Speed: Most Wanted (PS2)Need for Speed: Most Wanted performs poorly in the Lite ARMSX2 test, with the reviewer reporting about 20 fps and 35% speed. Shrek 2’s earlier EE cycle changes may still have applied.Pocket Duo Lite
Gran Turismo 4Gran Turismo 4 is well below full speed in the Lite ARMSX2 test. The reviewer reports roughly 35–42 fps and around 62% speed; no fix is shown. Shrek 2’s earlier EE cycle changes may still have applied.Pocket Duo Lite
Final Fantasy XFinal Fantasy X gets a positive verdict in the Lite ARMSX2 stream at 1×. The reviewer reports no slowdown in the shown overdrive sequence; later areas were not shown. Shrek 2’s earlier EE cycle changes may still have applied.Pocket Duo Lite
Fatal FrameFatal Frame has a slow cutscene but reaches reported full speed during the shown gameplay on Lite. The reviewer is unsure about later ghost encounters. Shrek 2’s earlier EE cycle changes may still have applied.Pocket Duo Lite
Dynasty Warriors: Gundam 2Dynasty Warriors: Gundam 2 reaches a reported 60 fps at 1× during the shown Lite combat. Later, busier battles were not shown. Shrek 2’s earlier EE cycle changes may still have applied.Pocket Duo Lite
