limitation, adult dating sims and visual novels appeared as a revival of 1980's adventure games and gained popularity, such as Dōkyūsei and YU-NO. After the PC-98 declined, many Japanese PC game developers shifted the game platform to video game consoles, except for eroge distributed by computer stores. Price war with DOS/V PCs In the 1980s and early 1990s, NEC dominated the Japanese domestic PC market with more than 60% of the PCs sold as PC-9801 or PC-8801. In 1990, IBM Japan introduced the DOS/V operating system which enabled displaying Japanese text on standard IBM PC/AT VGA adapters. Other Japanese PC manufacturers joined the PC Open Architecture Developer Group (OADG) organized by IBM Japan and Microsoft. In October 1992, Compaq released a DOS/V computer priced at compared to the lowest priced PC-98 at , causing a price war in the Japanese PC market. In 1993, Toshiba introduced DOS/V computers, Epson founded Epson Direct Corporation to sell DOS/V computers, and Fujitsu started selling DOS/V computers branded as FMV. In November 1992, NEC introduced a mid-range Windows PC, the PC-9821 which contained an Intel 386SX processor, a CD-ROM drive, 16-bit PCM audio playback, MS-DOS 5.0A, and Windows 3.0A. In January 1993, PC-98 desktops were expanded into three lines: a high-performance Windows-based line named "98MATE", a low-priced MS-DOS line named "98FELLOW", and an all-in-one desktop line named "98MULTi". PC-98s were still popular among Japanese users because they had many applications. NEC managed to adopt industrial standards and reduce costs. From 1993 to 1995, the PC-98 adopted 72-pin SIMMs, the 3.5-inch 1.44 MB floppy format, IDE storage drives, a 640×480 DOS screen mode, 2D GUI acceleration GPUs, Windows Sound System, PCI slots, and PCMCIA card slots. NEC had outsourced manufacturing of motherboards to Taiwanese companies such as ECS and GVC (acquired by Lite-On). Decline Aside from other Japanese domestic platforms which had disappeared, Windows 95 overturned the dominance of the PC-98. The difference in the architecture was not only ineffective for platform-independent environments but also increasing development resources to adopt them. During the development of Windows 95, NEC sent an average of 20 engineers to Microsoft's office in Seattle. Even though the PC-98 uses some IBM clone components, Windows requires the special driver or HAL to support its IRQ, I/O and C-Bus. The Nikkei Personal Computing magazine wrote, "The PC-98 features a number of MS-DOS applications, but there is no difference between PC-98 and PC/AT
