CRIWARE's logo

CRIWARE describes the technology they build. From the products to the services provided by CRI Middleware Co., Ltd. The goal of the CRIWARE brand is to convey the high-level of quality built into all of their products, the quick pace of their development teams, and the overall cost/performance ratios that can be expected when a customer uses their products.

The number of consumer game titles, arcade game titles along with other embedded systems that have been developed using CRIWARE currently exceeds 2,000 on a global scale (That includes Triggerheart Exelica and Triggerheart Exelica Enhanced). These results are testament to the high-quality and easy implementation of CRIWARE. All hardware that CRI's middleware resides on is first researched and examined thoroughly and then their tools are optimized for it; Fine tuned to guarantee that the highest levels of quality and performance can be provided to the customers. The CRIWARE logo is based on a television screen and a speaker. These symbols represent the areas that CRI excels in; audio and video. The reason why the television screen and speakers are depicted in white is to represent them as being in a standby mode, waiting patiently for the creators to fill in the color they desire. The dark blue represents CRI's never-ending quest for high-quality and technology, as well as their dedication to repaying the trust shown in us by their customers. The soft and gentle curves have been incorporated to express the flexibility and functionality of middleware.
