Wireless 360 Controllers Now On The Dreamcast

March 18, 2021 by 4 Comments

Perhaps the greatest convenience feature of modern consoles is the wireless controller. Eliminating the risk of tripping over cords and enabling play in all manner of poorly ergonomic positions, they added huge comfort to the console gaming experience. [ismell] was no fan of the Dreamcast’s original controller, and the cable was too short to boot. It was time to bring the 360 Wireless controller to Sega’s swansong.

Early attempts by [ismell] involved a Windows computer acting as a USB host for the 360 controller, which would then send out commands back to the Dreamcast via a Cypress EZ-USB FX2 microcontroller. If this sounds esoteric and messy, that’s because it is. It was also too slow to reliably work, as the Dreamcast’s Maple controller bus expects updates every millisecond, else it considers the controller disconnected.

Instead, a dedicated USB host was needed to speak to the 360 controller and also the Dreamcast. [ismell] landed on the MicroZed 7010, a System on Chip that also packs an FPGA on board. With Petalinux running on the board, it interfaces with the Xbox 360 USB wireless controller interface, and then sends the data out over a custom “network” driver that sends packets to the Dreamcast over the Maple bus.

It’s by no means a simple hack, and the MicroZed is far from cheap, but it works and works well as shown in the video below. We’ve seen other wireless controller adapters over the years, too – like the wild BlueRetro build. We always love to see a good retro console hack, so don’t be shy about sending in your own!

Dreamcast Controller Adapter Even Works With Mice

March 16, 2021 by 5 Comments

PC gamers have the benefit of a broad ecosystem of peripherals built to serve their gaming pleasure. As a bonus, if there’s something out there that doesn’t work with the platform, someone is likely already selling an adapter for it. Console gamers aren’t so lucky, and the vast majority stick with the factory standard controller. [megavolt85] isn’t one of them however, and spun up a multi-adapter for the Sega Dreamcast.

The adapter lets the player use a huge variety of controllers with the Dreamcast. There’s support for both PS1 & PS2 controllers, including vibration support, as well as MegaDrive & Saturn pads, too. PS/2 mice and keyboards can be used as well, and up to 16 VMUs can be hooked up as well. The adapter uses the STM32F103C8T6 microcontroller, which runs at up to 72MHz, giving it plenty of grunt to emulate the Dreamcast’s Maple controller interface.

We’ve seen other hacks of the Dreamcast’s controller bus, too; this custom controller implements the interface on a Raspberry Pi Pico. If you’ve been cooking up your own glorious Dreamcast mods, be sure to drop us a line!

A Dreamcast VMU With A Secret

November 14, 2017 by 8 Comments

Since the Raspberry Pi range of boards first appeared back in 2012, we’ve seen them cleverly integrated into a host of inventive form factors. Today we bring you the latest offering in this space, [Kite]’s Raspberry Pi Zero W installed in the case of a Sega Dreamcast VMU. The result is a particularly nicely executed build in which the Pi with a few of its more bulky components removed or replaced with low-profile alternatives sits on the opposite side of a custom PCB from a small LCD display.

The PCB contains the relevant buttons, audio, and power supply circuitry, and when installed in a VMU shell makes for a truly professional quality tiny handheld console. In a particularly nice touch the Pi’s USB connectivity is brought out alongside the SD card on the end of the Zero, under the cap that would have originally protected the VMU’s connector. Some minimal paring away of Sega plastic was required but the case is surprisingly unmodified, and there is plenty of space for a decent-sized battery.

The VMU, or Visual Memory Unit, makes an interesting choice for an enclosure, because it is a relic of one of console gaming’s dead ends. It was the memory card for Sega’s last foray into the console market, the Dreamcast, and unlike those of its competitors it formed a tiny handheld console in its own right. Small games for the VMU platform were bundled with full titles, and there was a simple multiplayer  system in which VMUs could be linked together. Sadly the Dreamcast lost the console war of the late 1990s and early 2000s to Sony’s PlayStation 2, but it remains a console of note.

VMUs are not the most common of gaming survivors, but we’ve shown you one or two projects using them. There was an iPod conversion back in 2010, and much more recently some mind-blowing reverse engineering and emulation on the original VMU hardware.

Thanks [Giles Burgess] for the tip.

Surfing Like It’s 1998, The Dreamcast’s Still Got It!

March 15, 2017 by 52 Comments

If you were a keen console gamer at the end of the 1990s, the chances are you lusted after a Sega Dreamcast. Here was a console that promised to be like no other, a compact machine with built-in PowerVR 3D acceleration (heavy stuff back then!), the ability to run Windows CE in some form, and for the first time, built-in Internet connectivity. Games would no longer be plastic cartridges as they had been on previous Sega consoles, instead they would come on a proprietary DVD-like Sega disc format.

It was a shame then that the Dreamcast never really succeeded in capitalizing on its promise. Everyone was talking about the upcoming Sony Playstation 2, and disappointing Dreamcast sales led Sega to withdraw both the console, and themselves from the hardware market entirely.

There remains a hard core of Dreamcast enthusiasts though, and they continue to push the platform forward.The folks at the Dreamcast Junkyard decided to go backwards a little when they resurrected the console’s dial-up modem to see whether a platform from nearly twenty years ago could still cut it in 2017. This isn’t as easy a task as you’d imagine, because, well, who uses dial-up these days? Certainly in the UK where they’re based it’s almost unheard of. They were able to find a pay-as-you go dial-up provider though, and arming themselves with the most recent Dreamkey V3.0 browser disc were able to get online.

As you might expect, the results are hilariously awful for the most part. Modern web sites that rely on CSS fail to render or even indeed to load, but retro sites like those in the Dreamcast community appear as they should. There is a video we’ve put below the break showing the rather tortuous process, though sadly they didn’t think to load the Hackaday Retro Edition. It does however feature the rarely-seen keyboard and mouse accessories.
