Tilefinch Brings a Modern Web Browser to the PlayStation Portable
Reading lead
Developer Steve Janovitz has created Tilefinch, a modern web browser for Sony’s more than 20-year-old PlayStation Portable. The handheld’s 333 MHz MIPS32 processor and, on most models, 64 MB of RAM are far below the resources expected by current browsers, so the project relies on lightweight components: Lexbor for browser rendering and QuickJS for JavaScript, alongside PSP capabilities such as hardware video decoding. The article presents this as a demonstration that modern web access may be possible on constrained hardware, and suggests similar devices could be worth exploring. However, the author did not have a PSP available to test the browser, so its rendering quality, speed and practical usability are not independently verified; the proposed relevance to other platforms is also speculative.

The Sony PlayStation Portable, better known as the PSP, is now over two decades old. In its day it was an impressive handheld gaming machine, not least because of the inclusion of wireless networking and a web browser.
We tried the browser back then, and it’s fair to say the experience was a little underwhelming. We’re thus mightily impressed at [Steve Janovitz], who has produced Tilefinch — a modern web browser for the PSP.
Depending on the model, the PSP came with a 333 MHz MIPS32 processor, and for all but the first model, 64 MB of RAM. Powerful back in 2004,but leagues behind something that would run any modern web browser. So how’s he doing it? The answer seems to be by careful choice of software components and use of the PSP’s built-in capabilities for jobs such as video decoding. The browser engine is Lexbor for example, while JavaScript is handled by QuickJS.

We don’t have a PSP to hand so we can’t tell how it would render Hackaday or even how fast it is, but we’re suitably impressed by this project. For PSP enthusiasts it’s a game-changing browser, but for us it also points the way towards web browsing being a possibility for other platforms. As the distinction between a high-end microcontroller and a low-end SoC becomes blurred, we’re starting to see exciting new hardware emerging with devices such as Espressif’s ESP32-P4 that, on paper at least, might be capable of running this browser. Exciting times in limited hardware web browsing might be upon us.

Concrete fact is a third-party modern browser for the PSP using Lexbor and QuickJS; no performance or rendering tests were run because no PSP was on hand, so the practical result remains unverified.
