The team left. Jun Nagashima stayed — and finished both versions himself.
By the time Popful Mail's PC-98 port was underway, most of the Ys III team had left Nihon Falcom. Jun Nagashima, the programmer, stayed. He wrote the code for both the PC-88 original and the PC-98 version essentially alone, with minimal support staff around him. Two platforms. One programmer. The game shipped in May 1992 — both versions complete. Watching someone finish a project when the team walks away is one thing. Watching them finish two versions of it is something else. It makes you wonder what counts as "enough people."
About this game
Released in 1992, Popful Mail is an action-platformer for the PC-98 that combined the battle system from Falcom's Ys series with side-scrolling exploration. Originally designed for the older PC-88, it was then redrawn in double the vertical resolution for the PC-98, increasing the available colours and detail in its cutscenes. Directed by Yoshio Kiya, the game became one of Nihon Falcom's lighter-toned adventures.
The Story Behind
Popful Mail was developed by Nihon Falcom and first released for the PC-8801 in December 1991. By that time, Japanese developers had largely shifted to the more powerful PC-9801 series — the PC-88 had launched in 1981 and was considered antiquated. The PC-98 version followed in May 1992, redrawing all graphics at double the vertical resolution and increasing the available colours. The development team used features from Falcom's Dragon Slayer and Ys series, including the battle system of Ys and magic attacks like those of Ys II. Director Yoshio Kiya, producer Masayuki Kato, programmer Jun Nagashima, and composers Atsushi Shirakawa and Mieko Ishikawa led the project. The PC-98 port was developed during a turbulent period at Falcom — most of the Ys III development team had departed the company, leaving Jun Nagashima working essentially alone as the sole programmer for both the PC-88 original and the PC-98 version with minimal support staff.
Tricks & Tales
The PC-98 version runs at 640×400 resolution with 16 colours, compared to the original PC-88's 640×200 with 8 colours. The largest visual differences are in the cutscenes. The game was distributed on floppy disks. Popful Mail later received ports to the PC Engine, Super Famicom, and Sega CD — the Sega CD version was planned to be a Sonic the Hedgehog spin-off but the concept was rejected by Sega of America. The PC-98 version was released on May 22, 1992. While the PC-88MC variant with a CD-ROM drive could theoretically play Popful Mail with CD-quality audio, Falcom never released the accompanying CD to enable this feature.
Collector's Guide
What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Popful Mail copies regularly.
Does Popful Mail for PC-98 come on floppy disks or CD-ROM?
The PC-98 version was distributed on 3.5-inch floppy disks. Floppy media degrades over time, so it is worth asking the seller whether the disks have been tested and can still boot the game. If the seller confirms the game was tested and runs, that is a good sign the disks remain intact.
Can I play Popful Mail on a modern PC without a PC-98?
The PC-98 is a unique architecture not compatible with modern IBM-PC hardware. To play Popful Mail today without the original machine, you would need a PC-98 emulator such as Neko Project II. The game itself is region-locked to Japanese PC-98 systems.
