GDEMU plus IDE MOD Possible ?

[Skoomadude]

Hello is it possible to use the ide mod (Dream IDE Reborn) along with the GDEMU connected at the same time ?

I have a Dreamcast with an Dream IDE Reborn Board Installed and a DUAL-BIOS Mod (Dreamboot No-GD-ROM and Stock Bios PAL). Now i picked up a GDEMU. Both Works fine but when i switch to the NO-GD-ROM Bios to Boot Dreamshell it cant Read MBR From LBA (IDE HDD) if the GDEMU is Connected. If i Disconnect it, it will boot fine.

Is there a way to avoid disconnect the GDEMU everytime i want to boot NO-GDROM Dreamshell ?

Thanks

at the moment it is impossible, GDEMU occupies the entire bus, master and slave

Oh ok that explains everything. Is
there maybe a workaround by somehow enable or disable a powerline to the gdemu by a switch or something ? if it gets no power it cant operate i guess ?

I discovered an adittional issue: The IDE Mod works only at ide HDD's. But when i use a Sata HDD's via Adapter (JM20330) Dreamshell Iso Loader and Settings freezes at the "Loading" Screen. But playing from RetroDream loader works. But the game is stuttering a bit o.O.

Any Idea about this ?

there are a lot of problems with SATA, I recommend using IDE
SATA has only one advantage, you can buy it in the store
but there are a lot of IDE disks at flea markets and the price is much lower than for SATA

In my expirience it is the opposite SATA are much cheaper then 2.5 ide on ebay o.O.

Do you have any idea about the first question about temporaly bypass the and deactivate the gdemu ?

power off is not an output, the GDEMU will receive parasitic power from the bus, which may cause it to break

put the dreamshell cdi in gdemu will normally load the hd ide.

funny you are a person, they tell you that GDEMU conflicts with HDD
what's the point of running DreamShell from an image if the HDD still won't work

I have gdemu and when I use the bios hack it does not recognize GD-ROM READER.
Test with bootloader in gdemu and see if it will work with original bios just a test.

why test something, I already told you that GDEMU occupies both channels, master and slave, so the HDD will not work
I spoke to Deunan Knute and he promised to fix it in the future

He decides what he really wants to use: the IDE that has great speed but cannot run games with CDDA or GDemu that works 100% on all games.

where is 100% from?
Chinese clones are not 100% compatible
HDD performs much better in many games than any ODE
if it was possible to combine GDEMU with HDD it would be the most ideal option
