at the moment I'm working a little with the custom firmware loader and have my ps1 and ps2 memory card in it again. ok for those with psgroove 1.1 Work and would like to see the PS1 / 2 Memory Card, you need the following entry in the Insert category_game_tool2.xml
After
Code:
<Query
class="type:x-xmb/folder-pixmap"
key="seg_sdpsp"
attr="seg_sdpsp"
src="sel://localhost/minis?category_game.xml#seg_sdpsp"
/>
now put:
Code:
<!-- PS1/PS2 MemCard -->
<Query
class="type:x-xmb/folder-pixmap"
key="seg_mcutility"
src="xmb://localhost/%flash/xmb/category_game.xml#seg_mcutility"
/>
Another Deteil category_game.xml found in the
Code:
MMS_MEDIA_TYPE_SYSTEM & sort = + Storage Media: StorageMedia.type & cond = Ae + Storage Media: StorageMedia.stat.mediaStatus% xCB_MEDIA_INSERTED + AGL + Storage Media: StorageMedia.type%% xCB_MEDIA_TYPE_PS3_BD xCB_MEDIA_TYPE_PS1_CD + AGL + Storage Media: StorageMedia.mediaFormat%% xCB_MEDIA_FORMAT_PS3GAME_BD xCB_MEDIA_FORMAT_PS1GAME_CD
there is more or less a query what the media terms PS1 and PS3 will be so recognized. But PS2 is not recognized and not represented there. Maybe this has now irgenteiner an idea what is about for the PS2 there must I hope this time my English is better
