What race directors say

"My compliments to your product and service. I have used RaceClocker for several events, and I have to say - I LOVE IT! Your program has made timing rowing head races very easy. It is easy to use, accurate, and probably the best feature is live results."

Gregg Hartsuff

Head Coach University of Michigan Men's Rowing

"We have been using RaceClocker for the past 4 editions of our annual ADR Regatta. Over the years we have seen it develop into a reliable and easy to use timing solution at very low cost. Among others live results and split times are what rowers enjoy at our event."

Giovanni Margaroli

Race Director ADR Regatta

"Thanks for a wonderful tool. We started using RaceClocker recently for our annual events as an upgrade from stopwatches, pen and paper and Excel sheets. It works smooth, simple, intuitive, accurate and easy. We spend a lot less time on post-race calculation and the live results are a bonus."

Below is a concise, user-friendly overview covering what such a pack usually contains, common kinds of patches, legal and ethical considerations, and practical tips for using one with Lemuroid.

The word "patched" does not change copyright law. Distributing a ROM pack—patched or not—is technically copyright infringement in most jurisdictions. Lemuroid is an open-source

Ethical stance: The retro gaming community survives because of preservation. If you genuinely love a patched fan-translation, buy an original copy of the game (if available) or purchase a modern re-release (e.g., Castlevania Advance Collection). Patches are meant for owners of original media.

If you own the original cartridges, you are legally entitled to a backup (in most regions). Use a device like the GB Operator (for GameBoy) or a modded PS3 (for PS1 discs) to create your own .chd or .gba files.
