The last releases of YY-CHR (C++ version) included a plugin called 2BPP NES (KONAMI-S), which allowed users to view (but not edit) NES graphics compressed with Konami’s run-length encoding (RLE). This plugin, however, did not get remade for YY-CHR.NET (C# version).

As such, this release brings a recreation of that plugin (using the plugin code template shared by YY) to YY-CHR.NET, along with adding two new features:

• Usage of a double height bitmap (split into two 128×128 bitmaps) in order to handle and display all the decompressed data.
• Information about the decompressed graphics (size in bytes, PPU address, data’s end type).

This compression format appears in many of Konami’s Famicom Disk System / NES (CHR-RAM) games, such as:

• Contra (USA) / Probotector (Europe)
• Salamander (Japan) / Life Force (USA / Europe)
• The Goonies II (All regions)
• Ai Senshi Nicol (Japan, FDS)
• Rampart (Japan)
• Lagrange Point (Japan)

The download includes both source code and compiled DLLs (two variations). For more information about the plugin, please check the READ ME file.
