I may edit later with more consoles but Dreamcast is my #1. It was the first with virtually all of the following:
It had a web browser with flash support,
That's. OK. I wouldn't really miss that feature if it wasn't there.
Nope. I have the first-party mouse accessory for SNES, Genesis (Megadrive), and 3DO. I know there was a first-party Playstation mouse too.
I dunno. The XBAND modem for Genesis and SNES had a keyboard (probably doesn't count since it's a third-party accessory). I'm pretty sure the N64 online service in Japan (Randnet) would have had it. Probably even the banking system for Famicom (NES).
...but Dreamcast had
Typing of the Dead! :awe:
a screen on the controller(with memory card inserted),
Definitely. Sounds like you know about the Pocketstation. For those that don't know, it's a Playstation memory card with a screen and buttons, but that's no use when it's inserted in the system instead of the controller.
Controller i/o was an N64 innovation. I'm glad it carried-over to practically every major system since (excluding PS2/3).
This was great. I realized I wanted something like that the first time I played
Star Fox 64 and I wanted to tilt my Arwing just a little.
a memory card that didn't lose the info it stored if it ran out of batteries,
Is this a reference to N64? I think only the unlicensed third-party Memory Paks (all third-party Memory Paks were unlicensed) used a battery. Nintendo's was an EEPROM chip, IIRC. Referring to the internal storage in some (mostly first-party) N64 games, some games used volatile SRAM with a battery, but most (including
Super Mario 64) use non-volatile EEPROM. Still others (like
Super Smash Bros.) use another type of non-volatile EEPROM that is sometimes referred to as "FlashRAM."
a rumble pack that did not need batteries,
Yup. Very cool. Still giving props to Nintendo for controller i/o.
dial up and broadband internet support,
This kicked ass.
DLC(often free) and a large selection of online multiplayer games in an era where other consoles did not have online games.
Yup. I wish the system caught on. RIP, Dreamcast.
