Hi! I just got a Dreamcast Dev Unit and a GD Writer form ebay. However, the dev unit does not come with any SDK software and SCSI HDD. Actually I am a newbie, but I already got some basic knowledge by reading this forum. Ok here is my question: 1. The serial of the dev unit is S524S086537. I assume it is set 5.24. So what SDK version I have to get? R9 or R10? 2. Is there any way to make sure I have the right version (5.24) by just look at the hardware inside the dev unit? Just in case to make sure no one swap any hardware before. 3. Is that ok to get a bigger side HD (eg. 9GB instead of 4GB). Can I really use ALL 9GB with NTFS format? 4. This maybe a stupid question. Now the dev is no HD inside. So is it possible to check if the dev uniit is work or not? eg. no one flash a wrong version firmware. Thanks for help.
