Hacking WiiFlow - an open source GUI USB-Loader

[drakorex]

Would it be possible for Wiiflow to have an override where even if neek is set to autoboot something, you can still go to neek system menu though Exit to Neek?

Hi !

I don't know why but the coverflow don't change (1/2 buttons) with the last official release 4.2.1.

I use the default theme.

An idea ?

Hi !

I don't know why but the coverflow don't change (1/2 buttons) with the last official release 4.2.1.

I use the default theme.

An idea ?

Yes it's because there is no default.ini in the themes folder to change coverflows. You can pick one up from abz masterpack extracted folder.

EDIT: Hooray we're back!! Hiya WiiFlow'ers!

 

[Kalidor]

Thank you !

Exact, the default.ini is not present.

 

[Th3-Blu3BoMb3r]

hey just out of curiosity has anyone heard about something called hyperspin?

i believe thats PC software for use with various emulators, looks sweet just too lazy to set it up

 

[somewhereovertherainbow]

you guys should search for - hyperspin the frontend and hyperspin project - good luck

 

[Th3-Blu3BoMb3r]

I've actually started working on it it's pretty sweet but lots of work I could use a partner in crime to help me along the way if anyone is down

I have that.. took me 5 months to rename everything and put in the right folders . Never again . I got a arcade machine at home

 

[VashTS]

ill mod from here...lets take this to PM for any further hyperspin stuff or make a new thread somewhere else. cool?

back to wiiflow now.

can be remedied
thanks

are you saying that loading GC games from an SD don't work? Or that if WiiFlow is on SD and you want to launch a burned GC DVD backup, that the game does not load?

Sounds like it's installing the cMIOS to be able to run the DVD-R GC backup but then not re-installing DML in order to run the GC game from SD.

matto21 do u have the dml.wad u want to use in "/wiiflow/mios" ?

I have so
"/ wiiflow / mios"
but not re-install automatically DML, in order to run the game from SD GC.

R1055 all ok

 

[spacepimp]

I'm sure many are aware, but it's new to me - at emumovies.com, There's a shedload large database of in-game footage for use with PC game-launcher frontends, such as hyperspin. If wiiflow could display the video, i believe it's MP4, or even a conversion of them -

there's an existing set of emulator per-game banners.

In fact they're better than banners, because they actually show you footage from the game!

In game footage in action from about 3.30 :



EDIT: It's good to see wiiflow is way ahead of the game
Although I like the idea of specifically showing detail of the controller when selecting 'sources' - maybe an idea for the full cover set?

 

[VashTS]

implementing this into wiiflow sounds awesome. FIX94 from the point of development, is it even possible for this much stuff? i know the wii has a tiny bit of RAM available.

im of course not asking you to do it, just if its technically even possible
