Hardware → Sega NAOMI Maple <-> JVS jumper mod
A simple hardware modification to disconnect the JVS controller from port 0 (port A on the Dreamcast). You just need solder jumper JP3 and switch it. This is a very useful for DreamShell and running Dreamcast games by it.
After this, you can connect all Dreamcast peripherals to port A. This will result in three ports available on the side board: A, B, and C. Port D is not routed on it, but may be available on the motherboard connector.
You need to find it on your revision of motherboard. The jumper pads is present on all NAOMI revisions. Here I will show an example on the most common version:

Hardware → Sega Dreamcast & NAOMI SCI-SPI Mod
This guide explains how to access the SH-4 SCI port on Sega Dreamcast and NAOMI systems in both UART/SPI communication modes. It can be used for debugging or connecting an SD card. In SPI-like mode, the SCI port can transfer data at speeds up to 1.5 MB/s, which is twice as fast as using the SCIF port for bit-bang SPI.

Hardware → New BIOS mod (unlock G1)
Данный мод теперь не актуален, если вы хотите сделать BIOS mod, то воспользуйтесь старой схемой.
Вам нет необходимости полностью переделывать свой старый BIOS мод, это просто доработка. А если у вас не было BIOS мода раньше, то берём MX29LV160, поднимаем 1-ю,12-ю,44-ю ноги накладываем на родной BIOS и аккуратно паяем. Всё остальное думаю понятно из схем.
Внимание: наличие оригинального биоса обязательно, ни в коем случае не отпаивайте его

Hardware → G1-ATA (IDE) adapter
This is a first version of G1-ATA adapter.
The printed circuit board is provided with small errors in size, so if you can draw yourself, do it better.
Or you can wait the new version of PCB from OzOnE.
And of course you can solder wires directly to the motherboard.
You can use IDE HDD (need external power) or CompactFlash cards (powered from DC).
Maybe some adapters IDE->SATA/SD etc will work too, but this is not guaranteed.
Prepare in advance for release DreamShell 4.0 RC 2 ;-)
