[self assigned] [no support requested] [tracking wip feature] derby owners club
Is your feature request related to a problem? Please describe. Derby owners club does not run all satellite systems, sync issue, limitation of current networking
Describe the solution you'd like make game fully playable and bootable by anyone without digging for days.
Describe alternatives you've considered considered? I bought the hardware. that's long gone

[one rom may be the server and the other may be the client reading some items shows there are two discs not just one]
make sure you have your hardware key to dump the roms from your drive.
took a quick look at nulldc bear because why not and its networking took a quick look at redream and a new compiled demul from may check demul video reference; https://youtu.be/jR4_2M1i2Qs?si=tCSuLgjCJcC-wAeU

======================================================== The how to so far:
Dump your roms legally make into mame format
then use the "mame extractor" to make it a dreamcast rom [naomi format? I'm not an expert here]
run flycast you need 10 instances [6 minimum], 2 for the terminal [it has multiscreen so maybe 1] and 8 for players

do a sensible thing way late, check image integrity. https://github.com/DerekPascarella/UniversalDreamcastPatcher#existing-features
check error codes for next hint: https://wiki.arcadeotaku.com/w/Sega_NAOMI_Error_Codes
save for later? https://github.com/mathieulh/SEGA_DIMM_CD-R
then open naiso, select your iso, paste your security PIC key, set the info file name to something that matches your current PIC, (if it's a 00 key PIC, that's usually ABC.BIN), paste a new key if you are using a non zero PIC, and click on "Start"
go down new rabbit hole: https://www.arcade-projects.com/threads/how-to-create-a-zero-key-pic-for-net-booting-and-cf-on-naomi-chihiro-and-triforce.6611/ [this cant be the issue can it? this is the easiest thing on earth to make] here are the tools incase anyone else needs it: https://github.com/mathieulh/SEGA_DIMM_CD-R

requires testing of multi-region bios and modified bios vs stock bios
may need to build tool for users to modify bios and dipswitches respectively, test mode button naomi 2 jumpers: https://www.youtube.com/watch?v=weOClPKwUEo
add note for something to check from user crediar/ kretiar on arcade community discord [triforce yet may explain the sync issue if wrong protocol or number set]
I also fixed something network related, apparently they expect the handles from sockets to be in range of 0-63, which on modern system never happens to get a handle that low in number. They basically use that number as multiplier into a buffer and when the number is higher than 63 then it falls back to 0 which of course is very bad.
Solving that issue actually made the key of avalon games at least boot.
Something very strange as well when using the V2 protocol you have to trigger an IRQ from the SP1 port once the DI command is done.

as per: https://forum.arcadecontrols.com/index.php?topic=166191.0
I've managed to make both PC's sync :
The weird thing is that flycast is not syncing the NAOMI2 title screen. It appears 1 second before on server PC and this makes the sync fail.
I've fixed this by entering and exiting the test menu on both PC's at the same time. When restarting the game the naomi2 title screen has appeared at the same time on both and then they've synced and gone ingame.
Did it work without having to do this on previous flycast versions? That would be a regression then.
nvm, already reported: https://github.com/flyinghead/flycast/issues/669
This was amazing to read, been down the rabbit hole myself recently….nothing works. Best of luck!!!
Only major update is that the YACardEmu can connect through serial https://github.com/DerbyOwnersClub/YACardEmu [however seems someone will have to compile it with a serial interface added]. the controller for doc is also not emulated/dumped and of course serial communication is still broken.
I was working on a card reader idea but i have no idea if it will work as you need the raw of the card.
Recently got the master to move past "checking network" blue screen, to "send go signal to slaves" blue screen...exciting. was using Python to network on the same machine.

would love to see a writeup on how you did it
Will Post here, its on other computer and was mostly done with Cursor agent, so i can't take real credit. The agent doesnt have the context bandwith to run with it. When I am done my real project I can sick Claud eon it, maybe a better result.
