I'm updating the DreamShell list of parameters based on the last boot loader released in the Swat Forum. The games were tested using this DS folder (That needs to be in the root of your SD Card/ide drive): http://titanide.kinghost.net/Dreamcast/DS.rar List of parameters: 102 Dálmatas – Async 8, 0x8c004000 18 Wheeler – Async 1, 0x8cfe0000 Advanced Wars 2 – Async 8, 0x8c004000 Alien Front Online – Async 1, 0x8c000100 Alone In The Dark IV – 0x8cfe0000 Another World – Async 8, 0x8c004000 Aqua GT – Async 8, 0x8c004000 Blue Stinger – Async 16, 0x8cef8000 Bomber He He – Async 8, 0x8c004000 BomberMan Online – Async 0, 0x8cef8000 Buggy Heat – Async 8, 0x8c004000 Cannon Spike – Async 1, 0x8c004000 Capcom vs Snk 1 – Async 1, 0x8c004000 Capcom vs Snk 2 – Async 1, 0x8c004000 Carrier – Async 8, 0x8c004000 Cave Story – Async 8, 0x8c004000 Charge And Blast – Async 4, 0x8c004000 Chicken Run – Async 8, 0x8c004000 Chu Chu Rocket! – Async 16, 0x8cfe8000, CDDA Crazy Taxi – Async 16, 0x8cfe8000 Crazy Taxi 2 – Async 2, 0x8c004000 Dangerous Toys – Async 8, 0x8c004000 Daytona USA – Async 8, 0x8c004000 Dead Or Alive 2 – Async 8, 0x8c004000 Deadly Skies – Async 8, 0x8c004000 Dino Crisis – Async 8, 0x8c004000 Divi Dead – Async 8, 0x8c004000 Doom Collection – Async 8, 0x8c004000 Draconus – Async 8, 0x8c004000 DUX – Async 8, 0x8c004000 Dynamite Cop – CDDA, 0x8cfe8000 Ecco The Dolphin – Async 8, 0x8c004000 Elemental Gimmick Gear – Async 8, 0x8c000100 Evil Dead Hail To The King – Async 8, 0x8c004000 Evil Twin – Async 2, 0x8c000100 Evolution The World of Sacred Device – Async 8, 0x8c004000 Exhibiton of speed – Async 8, 0x8c004000 Expendable – Async 16, 0x8cfe8000, CDDA European SuperLeague – Async 8, 0x8c004000 F355 Challenge – Async1, 8x8cfe0000 Fighting Force 2 – Async 8, 0x8c004000 Fighting Vipers – Async 8, 0x8c004000 Final Fight Apocalypse – Async 8, 0x8c004000 Flag to Flag – Async 16, 0x8cef8000, CDDA Flashback – Async 8, 0x8c004000 Frame Gride – Async 8, 0x8c004000 Gaunlet Legends – Async 8, 0x8c004000 GTA 2 – Async 8, 0x8c004000 Head Hunter – Async 8, 0x8c004000 Heavy Metal Geomatrix – Async 8, 0x8c004000 Jedi Power Battles – Async 8, 0x8c004000 Jet Set Radio – Async 8, 0x8c004000 Last Blade 2 – Async 8, 0x8c004000 Maken X – Async 8, 0x8c004000 Monaco Grand Prix 2 Online – Async 16, 0x8cfe8000 Mars Matrix – Async 8, 0x8c004000 Marvel vs Capcom 2 – Async 1, 0x8cff6000 Mortal Kombat Gold – Async 16, 0x8cef8000, CDDA Mr. Driller – Async 8, 0x8c004000 MTV SkateBoarding – Async 8, 0x8c004000 NBA Hoopz – Async 8, 0x8c004000 Nomad Soul – Async 8, 0x8c004000 Pen Pen Triathlon – Async 8, 0x8c004000 Phantasy Star Online v2 – Async 1, 0x8cef8000 Planet Ring – Async 8, 0x8c004000 Power Stone 2 – Async 8, 0x8c004000 Project Justice – Async 1, 0x8c004000 Propeller Arena – 0x8cfd0000 Quake 3 – Async 8, 0x8c004000 Quake – Async 8, 0x8c004000 Record Of Lodoss War – 0x8cfe0000 Red Dog – Async 8, 0x8c004000 Resident Evil 3 – Async 8, 0x8c004000 Resident Evil Code Veronica – Async 8, 0x8c004000 Rippin Riders – Async 8, 0x8c004000 Rise Of The Triad – Async 8, 0x8c004000 Roadsters – Async 8, 0x8c004000 Sega GT – Async 4, 0x8c004000 Shenmue 1 – Async 1, 0x8cfe80000 Silver – Async 8, 0x8c004000 Skies Of Arcadia – Async 8, 0x8c004000 Snow Surfers – Async 8, 0x8c004000 Sonic Adventure – Async 1, 0x8cfe0000 Sonic Adventure 2 – Async 8, 0x8cef8000 Soul Fighter – Async 8, 0x8c004000 South Park Rally – Async 8, 0x8c004000 Spawn – Async 8, 0x8c004000 Spec Ops II – Async 8, 0x8c004000 Speed Devils – Async 8, 0x8c004000, CDDA Spiderman– Async 8, 0x8c004000 Star Wars Racer – Async 8, 0x8c004000 Street Fighter III 3rd Strike – Async 1, 0x8c004000 Super Magnetic Neo – Async 4, 0x8c004000 Surf Rocket Racers – Async 8, 0x8c004000 Suzuki Alstare – Async 8, 0x8c004000, CDDA Sword Of the Berserk – Async 8, 0x8c004000 Test Drive Le Mans 24h – Async 4, 0x8c004000 Time Stalkers – Async 8, 0x8c004000 Tokio Xtreme Challenge 2 – Async 4, 0x8c004000 Tokio Xtreme Challenge – CDDA, 0xc0000100 Toy Commander – Async 8, 0x8c004000 Toy Racer – Async 8, 0x8c004000, NO CDDA TrickStyle – Async 8, 0x8c004000, CDDA Unreal Tournoument – Async 8, 0x8c004000 Virtua Striker 2 – Async 1, 0x8cfe0000 Virtua Tennis 2 – Async 1, 0x8c004000 Zombie Revenge – Async 16, 0x8cfe8000, CDDA Zusar vu – Async 8, 0x8c004000 I tested some of the online games using DreamShell + SD Card, here is what I found: Phantasy Star Online ver 2 - Works really well online but there is an issue where you can't revive other players. Monaco Grand Prix 2 Online - Works great online, without CDDA. Quake 3 Arena - Works great online, without CDDA. Planet Ring - Connects but you can't find other players, the games are always full. Toy Racer - Connects, you can chat but It freezes when you start a game. Chu Chu Rocket - Connects, you can chat but when you start a game you go back to the lobby. Windows CE games don't work on the SD Card, I have to test the online ones on ide.
