hello i have a piggyback install on my dc, a mx read-write bios chip a long ago. and after trying some compatible bioses avaible for flash, ive come across that the best (for me) is the link83 bios. a bios with devkit startup animation, region free, and with retail looking dc menu. the modifications i need to do are
1 direct boot mil-cd by default
2 dark theme 3d bios menu by default
3 remove vmu copy protection triggered by some games example soulcalibur
@japanese_cake bioses can have those three options i mention as selections but the bios it self isnt smooth as link83 one. the main problem with @japanese_cake bios is after i boot in gdmenu then select a game to play and want to reset with the button combo the dc wont reset and stay in black screen, needing a power cycle to boot again
or modify @japanese_cake devkit bios 1.031 two requests here
1 enable back sega logo
2 dark theme 3d bios menu by default

yeah i figured it would be. Use 1.031. I dont supply 1.032 due to issues. 1.031 should work fine.

However, this only fixes issue 1 not 2. Pretty sure 1.031 doesnt allow changing the colours.

i will test the 1.031. the 1.032 have the black screen issue when hitting the reset button combo. if 1.031 is free from this problem then it will be more close to what i want. thanks in advance

I have been hoping for a new bios from JC for a while now. My guess is he is just busy with real life now. Still waiting a year for news on his Bleemcast retail disc protections being removed as well.

if youre speeking about gdemu issues with bleem deunan will release new fw in a month or 2. some testers have already a prototype fw. as long is he ok its fine. the modifications i need to the bios can be enabled with hex edit. i just dont know what values i should modify and i think its dangerous to boot a console with messed up bios thats why i dont touch it. unless i get instactions from people that know about this stuff

Well that doesn't really help me out as I own a clone device which can not be updated.
