Lecture Traces Open-Source Handhelds From Korea's GP32 to China's Dingoo A320

The workshop, titled Designing Open-Source Handheld Game Consoles, was co-hosted by Chaihuo AI Base Vehicle and the Institute of Network Society at the China Academy of Art. The lecture, A Brief History of Open-Source Handhelds, served as the theoretical session ahead of a hands-on exercise. The speaker said published material on the subject is thin and much of the account is drawn from personal experience, so parts of it may not meet strict standards of verification.

The narrative is organised around the Open Handhelds website, now frozen as an archive and no longer updated, which lists seven machines. The speaker treated those seven as the main line of the category's first decade, from 2001 to 2010.

The earliest is the GP32, made by the Korean company GamePark, which later went through a split and reorganisation while keeping the name. The device resembled a rounder Game Boy Advance and used a Samsung processor; the speaker suggested Samsung, then a challenger in ARM chips, wanted a showcase application and found a partner in a little-known company. GamePark did not market the GP32 as open source. It offered a standard C software development kit, and enthusiasts could register on a website, download a launcher and run their own programs. The firmware itself was closed, so the GP32 does not fully match the open-source label later attached to the category. It sold in small numbers, in Korea and Europe, with the developer community concentrated in Europe.

Demand came from hobbyist scenes that already existed. Game Boy development tools such as GBDK appeared in 1995, and before flash carts were available hobbyists replaced the chips inside retail cartridges to run their own code. Software circulated through sites such as DevRS. The scene's most durable legacy is in chip music: Nanoloop, released in 1998, and LSDj, released in 2000, remain common tools for new chip musicians and for live performance, helped by cheap consoles and numerous clones. The speaker also counted Chinese fan-translation communities among the users who wanted programmable portables.

The 2003 Tapwave Zodiac, which the speaker used in its second generation in 2006, ran Palm OS inside a console shell with a joystick and four buttons and was sold as a games machine. It inherited the Palm software market, where users downloaded trial versions from stores such as Handango and PalmGear and then bought registration codes, a model the speaker described as a forerunner of Android handhelds.

Between 2005 and 2010 the machines were, in the speaker's term, genuinely open: Linux-based consoles beginning with GamePark's GP2X in 2005, followed by the Wiz and Caanoo on the same architecture. The GP2X required no account registration and emulators were ported to it in quantity, again largely by European developers. The wider background was the spread of embedded Linux through router, NAS and PDA hacking circles.

Chinese manufacturers entered through MP4 players. The Dingoo A320 was sold in a crowded domestic market and built on a reference design from the ODM HuaXinFei, also used by models such as the Gemei X760+. The speaker said Chinese hardware makers tended to treat such devices as standalone products and invested little in ecosystems. The community work happened elsewhere: the Rockbox project, known for iPod hacks, began targeting the Onda VX747, which used the same Ingenic processor, in 2008. That work fed into Zhou Yajin, later a founder of the security firm BlockSec and then a Linux kernel developer, porting Linux to the VX747 in 2009. Three months later, in May 2009, the Spanish developer Ignacio Garcia, known as Booboo, ported the kernel to the A320 with display and button drivers, creating an ecosystem that neither Dingoo nor HuaXinFei had planned.

The OpenPandora came from European distributors of the GP32 and GP2X who wanted a successor with fully open hardware, schematics included; it also drew on Sharp's Linux-based Zaurus PDA. Supply was a disaster: pre-orders opened in 2008 and about 6,000 units had shipped by 2013 through the German distributor, while buyers who ordered from the British distributor received nothing after it disappeared.

Prices divided the three regions, according to the talk: the Dingoo A320 sold for 599 yuan, about 80 US dollars; Korean machines sat near 1,000 yuan; European machines carried the highest premium. The speaker left the question of how to build such a device to the workshop's practical session.
