Half-Life Dreamcast: Part 2
-Mods
For a game that was never released this port has quite a vibrant modding community.
Black Ops: No saving but at least it lets your start at different sections. Other than that it's pretty good. I'll leave this one up to you.
Opposing Force: No saving and if you want to go back to a map you have to use a Dreamcast Keyboard to type in the map name and etc. Also includes some mods but they also need the keyboard. Skip This.
Counter Strike: I haven't played too much of it but so far it isn't CS. No saving. It's like a really crappy mod of Condition Zero Deleted Scenes. Skip It
Grunt: Haven't got this to work yet. I might talk about it in the next part if I get it working
Paranoia: God I hate this mod. I haven't got that far but so far it looks fullbright. For the love of god skip it.
They Hunger Trilogy: This is a really good port. The only thing wrong is that you can't die in the first Episode. Get it.
Blue Shift: Someone Put Blue Shift on a standalone disk. Yes. Really.
Join in for part 3... sometime...
I am genuinely curious!
And how do you play them on your Dreamcast? Do you burn a game CD with the mod files on it in place of the originals?
I can't imagine what would possess somebody to create a HL mod on the Dreamcast as opposed to the PC. It makes no sense to me. I have the DC version of HL, and "difficult to manage" would be a bit of an understatement regarding the realities of using a gamepad to play it.

Almost all Dreamcast systems are capable of playing backups on CD-R's (only cd-r's). If the image file is a cdi file then use Diskjuggler and when you put it in your Dreamcast it should work right away. If it isn't a cdi file then it's a bit more iffy. I can't find a working way to make a mod working on HL Dreamcast (believe me I tried).
There is just something about playing it on a Dreamcast. It's magic (You know. I cannot believe its not so :P). I found the controls to actually work pretty well given the controller. The only thing that's not so great is the "shift" function.
