LEMON BLOG

Lemon Web Games just went through one of its biggest upgrades ever, bringing massive performance boosts, new emulator platforms, and smarter in-game systems. But before you dive back into your favorite retro titles, there's one small thing you need to do—clear your browser cache.

The Everyday Challenge of Accurate Coding - Every hospital department knows the importance of accurate ICD coding. Whether it's the medical records unit preparing discharge summaries, physicians documenting diagnoses, or billing officers handling claims, every entry must align with international coding standards. Yet, the process often feels slow, repetitive, and prone to human error. Searching through complex ICD databases can take time, and misclassification can cause claim rejections or inaccurate health statistics.

For quite some time, our LEMON WEB DICOM Viewer has been running smoothly on Cornerstone v2 — the trusted imaging library that made web-based DICOM viewing simple, fast, and reliable. But as imaging standards and browser capabilities evolve, it was time to give the engine a serious upgrade.

If you've ever wondered who owns a website, where it's hosted, or how its DNS is configured, you're not alone. Whether you're managing your own domains or just curious about what's happening behind the scenes of a site, having quick access to this kind of data can be incredibly useful. That's exactly why we created the Domain IP Checker — a simple yet powerful web app that puts all the essential technical information at your fingertips.

In today's digital world, email isn't just a communication tool — it's the frontline of your organization's identity. Unfortunately, it's also one of the easiest channels for attackers to exploit. From phishing campaigns to domain spoofing, cybercriminals love impersonating trusted brands to trick recipients. That's where SPF, DKIM, and DMARC come in — the trio of DNS-based security protocols that help your emails prove they're legitimate.

When you open your browser's DevTools and see a mysterious request like /cdn-cgi/speculation, you might wonder — what on earth is that? If you're using Cloudflare, it's not a bug or a random file someone snuck in. That little request is part of Cloudflare's Speculation Rules — a smart, behind-the-scenes optimization system that quietly makes your website feel faster and smoother to visitors.

I've learned something the hard way recently — caching can be both your best friend and your worst nightmare. One day, everything on my website was lightning-fast. The next day, every single js-dos game just… died. No warning, no clues — just a cryptic WebAssembly error that sent me down the rabbit hole.

Running a live TV streaming page like LemonWeb WebTV is never as simple as just embedding a video. Sometimes, streams change on the broadcaster's side, and other times browsers enforce rules that can cause unexpected issues. That's exactly what happened with the TV3 channel.

For a long time, one of the biggest frustrations with playing DOS classics on LEMON WEB GAMES was the save system. Sure, you could spend hours blasting demons in DOOM or navigating dungeons in Stonekeep, but when you came back the next day… your save was gone. Not fun.

In today's fast-paced, mobile-first world, the way we share contact information has evolved far beyond stacks of printed cards. Enter the QR Name Card Generator, a lightweight web app designed to make networking seamless, professional, and digital. Whether you're an entrepreneur, a corporate professional, or a freelancer, this tool makes it easy to create, share, and save your very own digital business card.

If you've been following Lemon Web Solutions, you'll know we've been cooking up quite a storm lately. The past week alone has brought some major changes to both our Web Apps and Web Games sections — from a flood of new titles to behind-the-scenes improvements that make the experience smoother and smarter. Let's dive into the highlights.

A Blast from the Early '90s - Long before the days of Windows 95, XP, or even Windows 11, there was Windows 3.11. Released in the early 1990s, this operating system represented one of Microsoft's first real steps into graphical user interfaces that everyday users could enjoy. Back then, navigating your PC meant using Program Manager, working with groups of icons, and relying on the trusty DOS underneath to get things moving. Fast forward to today, and thanks to modern web technology, you can now experience Windows 3.11 directly in your browser—no floppy disks or vintage hardware required.

If you've ever tried running PS1 games on EmulatorJS, you've probably noticed something… missing. Out of the box, EmulatorJS doesn't map L1/L2/R1/R2 in its touch overlay for the PSX core. That's fine for some titles, but the moment you boot anything like Resident Evil 2, those shoulders suddenly matter a lot. Google around and most posts say the same thing: "Use a Bluetooth gamepad." That's a great option—until you're on a phone, on the couch, with no controller in sight.

Why the Update Was Needed - If you've been tuning into LEMON WEB-TV lately, you might have noticed that the TV3 channel wasn't behaving as it should. The previous source we were using occasionally threw playback errors, causing interruptions and frustrations. Nobody enjoys buffering or error screens when they're in the middle of their favorite shows, so I knew it was time to act.

Healthcare is moving fast into the digital age, and one of the best ways to show what's possible is through working demos. That's where DrKiddo comes in—a proof-of-concept application designed to showcase how hospitals, clinics, and healthcare providers could leverage modern app technology. While this demo doesn't represent the full picture, it gives a solid glimpse of what's possible when technology meets patient care.

A Nostalgic Journey - Back in 1995, Microsoft released Windows 95 and changed personal computing forever. For many of us, it was our first real step into the world of graphical desktops, multitasking, and the now-legendary Start menu. Fast forward almost three decades later, and the same experience can now be revisited without digging out an old beige PC tower. At Lemon Web Solutions, we've brought Windows 95 back to life in the most accessible way possible—through a fully web-based emulator. 

If you've ever used an external GPU (eGPU) with Windows, you'll know it's not always a smooth ride. In fact, I was consistently hit with Windows crashes and system instability whenever I disconnected my eGPU setup.

For years, one of the biggest challenges faced by patients and healthcare professionals in Malaysia has been the lack of transparency when it comes to drug pricing. Many people have no easy way of comparing medicine costs across different products, packaging, or brands. Recognizing this gap, the Malaysian Drug Price Checker System was developed to provide the public with quick, reliable, and updated access to drug price information sourced directly from the Ministry of Health Malaysia (MOH).
