My GBA Harvest Moon friends of mineral town's save data is always corrupt How can I stop this?

This happened to me and sadly there is no particualar way to stop this. There are only a cuple of choices you have one is to continue making new games and playing till it corrupts again when you save it. Another is to never turn your game of and to keep it on the charger, but this can burn your screen or overheat your game and the other choice is to buy another Harvest Moon if you can't find them at you local game store try and order it in if your intent on buying it.

What is binary encoded hexadecimal?

There is no such thing as a binary encoded hexadecimal value. The encoding is simply the representation of a number. E.g., the symbol 42 is not a number, it is merely the representation of a number. Forty-two is an actual number. This is because 42 is only the number forty-two when the digits are base-10 (decimal). In octal notation, 42 is thirty-four and in hexadecimal notation 42 is sixty-six.

Humans use decimal encoding to represent numbers simply because that's the way we were taught from an early age. We consider them easy to work with simply because we consider it easier to work in powers of 10. However, it's really no easier than working in powers of 5 or 12. Before decimalisation became the norm we actually used sexagesimal, base-60, because of its high divisibility (it's the lowest number that has all the factors 2, 3, 4, 5 and 6). Hence there are 60 seconds to the minute, 60 minutes to the hour, 24 hours in the day (2x2x2x3) and 360 degrees in a rotation.

Binary and hexadecimal are simply different ways of encoding the same number. Computers only understand binary, but binary notation is tedious for humans because there are only two symbols to work with. Higher bases allow us to work with numbers more quickly because there are more symbols to play with and therefore more values we can represent with just a single digit. However, any base that is itself a power of two gives us a very simple conversion to and from binary. That is; base-4, base-8 and base-16 are more closely related to binary than is decimal.

For instance, two binary digits have four possible combinations, each of which can be represented by just one base-4 digit. Three binary digits have eight possible combinations each of which can be represented by just one base-8 digit (octal notation). It therefore follows that a single base-16 digit can represent any combination of 4-bits. Since a byte is typically 8-bits in length, a hexadecimal digit is known as nybble because it is half-a-byte.

Knowing this we can easily convert any number from hexadecimal to binary and back again. And if we can do it easily then a computer can do it just as easily. Converting to and from decimal is not so straightforward, but the computer can be programmed to do that for us as well, since decimal is the notation we're more used to. But when we want to instruct the computer in its own language, hexadecimal is easier to work with than decimal.

What is the connection of an array in data structure?

Both are aggregates of elements of the same type. The main difference is that an array allocates elements contiguously thus there is no need to maintain links between the elements; each can be addressed by its offset from the start of the array. A structure, however, allocates elements non-contiguously, and must maintain links (pointers or references) within the elements in order to navigate from one element to the next.

What algorithm does RIP use?

I think that you are meaning acromym. RIP means rest in peace.

What is output stream?

Messages and other output data that an operating system or a processing program displays on output devices. It is a means of writing data in a byte-wise manner to a target.

What are the different types of queues?

A priority queue is a queue in which each element is inserted or deleted on the basis of their priority. A higher priority element is added first before any lower priority element. If in case priority of two element is same then they are added to the queue on FCFS basis (first come first serve). Mainly there are two kinds of priority queue: 1) Static priority queue 2) Dynamic priority queue

Where can you download Hedgehog Engine?

Hedgehog Engine is a progamming language and graphics program with a special SEGA light bounce engine. This engine is slightly hard and can be received at either an online site, or official Sonic site.

Computer A has an IP address of 169.254.45.21 what does this mean?

This is an APIPA (Automatic Private IP Addressing) address. When Windows computers can't get an IP address from a DHCP server, they automatically assign themselves this address.

Which distributions of Linux are most suitable for multimedia education and programming and are available in multiple languages?

Most Linux distributions can handle most of those tasks just fine. The one major hurdle would be inter-language support. Ubuntu, Debian, Fedora, and OpenSUSE all have excellent translations in a wide variety of languages. They include or make it easy to install all of the multimedia codecs, compilers and IDEs, and have a large selection of educational Linux programs. Ubuntu even has a variant designed especially for education, know as Ubuntu Education Edition (formerly Edubuntu).

What shows up on your internet bill?

How much it's going to cost and how much data you have used.

What is best for managing quantitative data?

Microsoft Access 2010 Access helps you keep track of large amounts of quantitative data,such as products inventories or employee records.

Difference between interrupt and subroutine in computer?

interrupt is a signal caused by I/O devices where as subroutine is a part of the program which is excuted rapidly

Does Glitch City corrupt your file on Pokemon Red and Blue?

no it doesnt corrupt your game but it does freeze it but dont worry about your save :)

What is modeling language?

A modeling language is a special purpose computer language (but not actually a programming language) for describing real world systems (e.g. electronic, mechanical, aerodynamic, hydraulic, chemical, atomic) to a computer so that it can create a mathematical model of the system and perform simulations, so the behavior of the system can be determined without having to go to the expense of building actual experimental prototype models and testing them in the real world.

Such languages are very important, especially when actual real world tests are either extremely dangerous and/or prohibited (e.g. nuclear explosive tests which have been banned in most countries by international treaty are all done now by computer simulation using a few modeling languages developed between the late 1950s and early 1990s using highly parallel very fast supercomputers). But they are also important for bringing new products to market quickly and at low cost.

How many different types of constants are there in COBOL?

there are three types of constants in COBOL

1. numeric literals

2. figurative constants

3. non-numeric literals

How do plotters work?

A plotter is an output peripheral device used with a computer, that can be likened to a printer. However instead of printing text or images, a plotter is more usually used to draw up technical plans and blueprints.

Instead of the print cartridge found in a printer, a plotter commonly uses a pen, although as will become apparent other implements can also be used in place of the pen. If you want to put a mark on a piece of paper with a printer, at a specific point, for example printing off some text, you need to make specific coordinates for where the text will end up on the page. When a printer sets to work, the paper feeds through the printer in a single pass, until the correct place down the length of the paper is found. Then the print head will move across the paper to the correct point and the printing will begin. If a whole page is to be printed, the print head will move across line by line until the text is printed. With a plotter, a similar method of moving the paper and pen holder are used to allow the pen to be in precisely the right point at the right time. However the order of print is different from a printer. The pen does not start at the top right moving to the left and then down a line. The plotter takes the whole image data, then calculates a path for the pen. While the path for the pen may look complicated while the pen is in motion, In fact the plotter has calculated the shortest route for the pen, that involves the least amount of crossed lines as possible. This not only makes the path more efficient, but also ensures there is the least possible chance of the final drawing getting smudged. As said earlier more than just pens can be employed, for example some plotters are used with small knife blades that pivot to follow the path of the plotter. These 'drag knife' cutters are used for such tasks as cutting out vinyl sheet to make custom signs, like the type seen on the sides of vehicles to advertise the details of a company, or tradesman.
